Bryopsis Algae Control Method Worked

A while back I posted on a method for bryopsis algae control, that involved using Kent Marine’s product Kent Tech-M. And in that post, I also told you that one of the exhibits in my care was a 900-gallon reef tank with a persistent bryopsis algae problem, and that I was about to use this method to eradicate the bryopsis algae from my tank.

And . . .

Drum roll please. . . . . . . . .

It worked!

Yes, it worked quite well. Before treating the tank with the magnesium supplement (Kent Tech-M), we did the following important steps to prepare:

PREPARATION STEPS
Step 1: performed two 35% water changes to help up the magnesium level to the normal 1,300ppm and to lower the phosphate level;

Step 2: Manually plucked/removed as much bryopsis as possible while the water level was down (during the water change). We did this during both water changes over a period of one week.

Step 3: stormed the tank with a powerhead on a stick to help get as much detritus out of the tank as possible. We have 4 filter socks in the sump that catch it quite efficiently;

Step 4: Replaced the Rowaphos media (a.k.a. ferric oxide) in our chemical filter (Precision Marine SR55P Professional Series Substrate Reactor), which helps to insult and stress out the bryopsis algae.

Step 5: Began dosing kalkwasser (saturated solution of calcium hydroxide and R.O. water), which precipitates out phosphates so that the protein skimmer can remove them. It also elevates the pH to 8.3-8.5, which helps inhibit the growth of unwanted algae such as bryopsis and hair algae. And kalkwasser also helps to elevate alkalinity, which also helps inhibit unwanted algae.

Step 6: Turned off the activated carbon filter. This is just a hunch, but since the active ingredient in Kent Marine’s Tech-M magnesium supplement is not known (that which eradicates the bryopsis), I certainly didn’t want the activated carbon to remove it. Originally, people felt it was the elevated magnesium level that was doing the work, but after multiple methods of raising the magnesium level produced inconsistent results, it was concluded that Kent Marine’s Tech-M product worked the best because of some mystery active ingredient.

Now that the preparation steps were completed we were ready to begin dosing the Kent Tech-M (magnesium supplement). The main instructions are to make sure that you do not raise the magnesium level by more than 100ppm per day.

So I went ahead with dosing the tank to raise the magnesium level by 100ppm per day until the magnesium level was between 1600-1800ppm, and in one week the bryopsis dropped to less than 50% of what it was before dosing. And by two weeks, 99% of the bryopsis was gone from the display tank. I was quite pleasantly surprised.

Overall it took 2 weeks and the Bryopsis is now gone. It is my feeling that the aggressive manual plucking/removal was a critical step to insulting/stressing the bryopsis. And remember we did this just prior to changing out the Rowaphos media (lowered phosphates to zero) and the subsequent dosing of the magnesium supplement.

We will see what time will tell. I have heard of the bryopsis coming back after a successful treatment, so the constant vigilence will continue – as it always does with a truly successful saltwater aquarium.

Please comment and share your experience with hair algae or bryopsis and how you went about it and what happened.

There are all kinds of algae problems an aquarist can experience in keeping saltwater aquariums, particularly with reef tanks. But none of them can be as nightmarish as Bryopsis.

Unlike most other algae, such as hair algae or cyanobacteria, Bryopsis does not respond to most removal methods. Even a normal algae problem can be extremely frustrating or even lead to someone giving up and shutting down their tank. But that doesn’t have to happen. There is a solution and I’m going to share it with you here in just a moment.

Typically, most algae problems such as hair algae or cyanobacteria, can be solved with a combination of:
- elevated pH
- increased water circulation
- removal of phosphates and nitrates
- removal of detritus, and
- addition of algae grazers (tangs, hermit crabs, snails, emerald crabs, urchins, sea hares, etc.)
- manual removal by humans (i.e. plucking, scrubbing, siphoning, etc.)

But Bryopsis is different, as it does not respond to these methods. Actually, it can often grow even more because of such methods (especially manual removal, which can feed asexual reproduction via fragmentation). And even biological controls such as adding grazing invertebrates and tangs is not only not very effective with Bryopsis, but it can be expensive (them critters ain’t cheap).

I wish I could say it was my idea – far from it. In fact, I have been dealing with a bout of Bryopsis recently in our 950-gallon saltwater reef exhibit at the Ocean Explorium, where I am Curator. And I was researching solutions to my problem when I cam across this solution. Here’s the link.

http://reefcentral.com/forums/showthread.php?s=&threadid=1113109&perpage=25&pagenumber=1

It explains the whole process in fair detail, with photos of results, showing the Bryopsis dying off and disappearing as a result of the treatment. I’ve also done more research on this method (thank you google) and it has actually been widely used with consistent successful results. And yet, it is a mostly unknown method.

Most people who get cursed with a Bryopsis algae outbreak, work like crazy for long periods of time, getting very frustrated, and still not even make a dent in the problem. Bryopsis algae outbreaks are usually caused by a new addition, where the algae comes in as a hitch hiker on a new coral or piece of live rock, or even a snail shell. So I’m glad I found it and even more glad to share it with you. Please be sure and share it with your friends too.

The method uses increased Magnesium levels for three months (1600ppm compared to the normal 1300ppm), to bring the Bryopsis to its threshold for binding Magnesium. This causes the Magnesium to then perform as an enzyme inhibitor, making the Bryopsis shut down and die off. Once this happens, the grazers in your saltwater aquarium will clean up the remains.

Point of caution: Be sure not to raise the Magnesium level by more than 100ppm per day.

Please post a comment here on the blog to share your feedback, or to tell your story if you are having any problems or frustrations with your saltwater aquarium. We would love to help you out in any way we can.

My tank is overheated – What caused it?

As the Curator of the Ocean Explorium (New Bedford, MA), I am responsible for multiple marine aquarium exhibits.  Two weeks ago, I got one of those phone calls no one wants to get.

It was the weekend and I was enjoying my time off.  As I listened to the aquarist describe the problem, her frustration was high.One of our aquarium exhibits was up to almost 90 degrees F!  It was the sea scallop exhibit (normally at 58 degrees F).

The aquarist had just completed a water change AND she did complete the “check out” procedure we always do when leaving for the day.  And then she went home.  But … during the “check out” process, instead of looking at the temperature controller to confirm that the chiller was on, she looked at the power plug (which she had unplugged during the water change).  The only problem was that the plug wasn’t plugged all the way in, thus, the chiller was not on and the tank overheated to 90F (instead of 58F).

Saltwater aquariums, and all aquariums for that matter, are subject to inherent vulnerabilities, which, if not addressed and accounted for, may lead to the demise of your aquarium’s inhabitants.  So what are these inherent vulnerabilities?

Well, before I get into it, let’s just say they are simpler than you may think.  You might be thinking of the 100 things that can go wrong in a saltwater aquarium.  Because, lets’ face it.  Keeping saltwater fish and/or reeftanks involves solving a lot of problems.  After all, there is nothing like a big problem to help you really learn your lesson and improve your skills of problem solving.  At the end of this post, I’ll tell you a brief story of one recent nightmare that was a perfect example of not doing a proper “check out”, and how it would have caught the issue and prevented the loss of animals.

But first, back to the mistake of only focussing on problem solving.  Even if you only focus on becoming great at problem solving, you will waste a lot of time dealing with problems that could have and should have been prevented.  So now you’re thinking you should be focused on the prevention of problems … and you’d be right.

So what is my big secret to how to prevent over 90% of the inherent problems that come with keeping saltwater fish and reef aquariums?

When I tell you my secret solution, you’re going to say to yourself “that’s obvious” or “that’s so simple”.  And again, you’d be right.  So here it is.

My secret to preventing over 90% of all problems that are inherent with saltwater aquarium keeping is … “check in …. and check out”.

See, I told you it was going to sound simple and obvious.  Most problems that occur in keeping saltwater aquariums are preventable … by far.  If you want to see consistent problems, floods, broken equipment and loss of valuable saltwater fish or corals, then watch what happens when you don’t do a proper “check in” and “check out”.

And the key to doing a proper “check in” and “check out” is to turn it into a written recipe or procedure that you go over EVERY SINGLE TIME you work on your tank(s).  The key here is that it be written out as a check list, SO THAT YOU DON’T FORGET ANYTHING.  In fact, because you’ve written it out (post it on the wall in your fish room or on the cabinet door under your tank, etc.), now you no longer have to worry about forgetting any of the key steps in this process.

This whole ‘forgetting things’ is usually the biggest source of nightmares, accidents, leaks/floods, and problems in saltwater aquarium keeping.  In my aquarium consulting business, we service large, high-end saltwater aquariums (typically costing over $50,000), so you can imagine how important it is to prevent problems.  When we come to service a client’s tank, the first thing we do is go through our “check in” process.  We use a simple written check list for this, and you’d be surprised how many items are on the list (it’s over 25).

But the great thing about having this list is that you don’t miss anything, and you don’t have to think.  You just go down the list and check them off.  Save your thinking for problem solving.  Yes … that’s right.  Even after you adopt a strict and consistent routine of doing a thorough “check in” and “check out”, you will still have problems to solve … just A LOT LESS of them … a lot less.  I mean, even in the story I told at the begging of this post, a problem still occurred even though we were using a “check out” procedure … it just wasn’t followed correctly.  This is where the human error part of the equation comes into play.  We humans make mistakes and when we’re in a rush we take short cuts … which is one of the rules of proper “check in” and “check out” – no short cuts.  Always follow the procedure.

So you’re probably wondering if we lost any animals with that big of a temperature spike.  The answer is yes.  We lost four scallops, but it took them a few days until the effects of the temperature spike to do them in.

Stay tuned for more, in upcoming posts, as I’ll go into detail on how to do a proper and thorough “check in” and “check out”, and exactly what to “check” for.  Meanwhile, go to www.saltwateraquariumsecrets.com and sign up so that you don’t miss anything.  Also, you can click on the orange RSS button at the top of this page to be notified whenever we post new material here on the blog.
