Well guys today I was checking out my nano tank like I always do and to my surprise I find what appears to look like BBA on the filter out take. I'm already battling green string algae on my moss and slowly creeping. What should I do?!? I looked and can't find it on anything else other than the filter outtake so I removed that piece and put it in a bucket with hydrogen peroxide it quickly started fizzing.

Sadly it is BBA like the others have said, a good thread to check out in the "One-Two Punch", I am testing it out now in one of my aquariums, so far the first treatment has cleared up the BBA but the BGA seems unaffected. You best bet would be to try and manually remove as much as possible, disconnect your filter and clean it with and H2o2, this will help clean out your filter tubes from BBA. The biggest success I have had keeping BBA in check are TSAE.

I took out the filter outtake and return hose and have them soaking in h2o2. Almost immediately the algae turned a clear color and is deteriorating. I really hope it doesn't spread in my tank. My last resort would be the one two punch method but this is occurring in my RCS tank and many have reported heavy shrimp casualties with the method so I'm definitely going to be cautious.

You could build a shrimp trap and store them in a bowl of water for an hour while you treat your tank. If it is on your intake and out flow hoses more than likely it is also inside your filter, so you will want to clean this with H2o2 as well.

There's no light in the filter so there's no BBA.
The tubes are a clear green, best bet is spores have gotten down the tubing and into the filter. You can believe as you wish but when I had BBA I tried the blackout method and BBA does just fine in near darkness, you would be surprised how little light it needs. But do as you wish. Might take you ten minutes to clean it, not that big of an investment, if you ask pretty much anyone on this forum if they could spend ten minutes to help prevent the spread of BBA in their tank if they would do it, and I bet the majority of them would.

Hello,

I know how you feel regarding BBA

What you need to do as the first step is to double-check your CO2 levels.. and double-check it again. Is it stable? As in, is your drop checker always a green colour during lights-on. Plants require, therefore MUST HAVE, as close to as a stable CO2 level as possible - major fluctuations in CO2 levels can have a negative effect and benefit algae growth.

Next.

Seachem Flourish EXCEL.
Using this is much safer than H202 and/or bleaching!

This is a great product. This kills off all BBA GUARANTEED. The best way to administer this is via a syringe (just a normal plastic one is fine).

1) Turn off filter and all water flow.
2) Fill syringe with Flourish Excel (dependent on tank size - read label).
3) Squirt the Flourish Excel SLOWLY over the affected areas where BBA has taken over.
4) Wait 10 minutes making sure there is no flow in the water - i.e. the water is still.
5) Power up all your filter(s) and pumps.


Then, within 24-72 hours (depending on how badly the BBA is), the BBA should turn from dark green/black to blue/purple/red. Then it will disappear.

According to many sources, BBA is caused by low levels of CO2 or fluctuating CO2 levels. Just make sure you are pumping a constant level of CO2 into the tank (i.e. the drop checker is a lime green). Obviously tanks don't require CO2 during night-time.

Also, give your plants plenty of nutrients - try and dose using the EI method if you can, this is the best way to dose your tank and has worked extremely well for me. And for the lights, well, definitely no more than an 8 hour period.

One final note. The Seachem Flourish Excel is not a permanent fix to your BBA problem. The BBA may come back if you do not get the balance between CO2, nutrients and light correctly. Also, continue to dose Flourish Excel daily as well as using pressurised CO2 with a decent regulator.

And the one thing that people always think is not important to do..

WATER CHANGES! - Trust me, waste products in the water (e.g. Ammonia) favours algae growth. Do a weekly water change (50% if dosing the EI way for nutrients) and that'll help a lot!

Best of luck,
Dan
