BBA issue.

[JadeButterfly]

Hey all,

I'm starting to get BBA on my driftwood...just the mini BBA...nothing too bad.

BBA is related to CO2. But last week's water change, i manually remove the BBA...and jacked up the CO2...this week I'm a little fustrated because my fish will start surfacing near the last 2-3hour of the lighting period...

but the BBA continues to come back. and comes back at the same area of the driftwood. this is only a minor BBA issue that occurs in a particular area of the driftwood..

So what should I do? I can't really increase my CO2 anymore (i need to start decreasing it lol)...and my fert dosage should be pretty good.

50G.
2x96W @ 11hr a day.
1/2 tsp KNO3
1/8 tsp PO4
10ml TMG in between.

(the dosage may seem high, but I never had a problem with it so I try to just stick with it)

thanks.

Re: BBA issue.

That's a lot of light.
How's your surface movement?
You might increase it and then increase the CO2.

Your fish should not be up at the surface if there's some decent surface movement.

Re: BBA issue.

I do have the outtake near the surface..and have a surface extractor which causes surface movement.

my main question really is, why is BBA still growing when fish are gasping (ie. CO2 is high)

I'm still waiting for my viewtainers to come in so I can make a venturi reactor (currently using inline reactor). I will change my output to a spraybar once I get the venturi in.

hopefully that can solve the BBA issue.
