I have 3 bulbs on each 3' section 6500k, no co2 and I was using seachm flourish (haven't lately). I stopped when the algea bloom started. I just scrubbed the driftwood, scrapped all the algea off the glass, got as much off the plants as I could, scooped it out of the sand and did two 50% water changes. I'm about to put the driftwood back in.Corvus wrote:Ah... it's even a planted tank (your fahaka seems to be a nice one)... that's good news...
I hope you have a green thumb.
Promote plant growth and the Cyanobacteria will go away with a little patience.
Do you use bulbs for plants, CO2 and aquarium plant fertilizer?
If not, you may want to consider that.
Plant growth will also help somewhat with the phosphate levels.
I only have the BGA in the one tank, the other tank never had that problem and it has the same level of phosphate. The only difference between the two is the ph. (see above), gallons and the substrate. I use the same kind of lighting on both tanks.Troender wrote:With that number of phosphate, there's a chance for BGA if you have low nitrates, which you have. Believe it or not, but higher nitrates will help (or at least is supposed to help - I haven't tested it myself).
The other tank without the BGA is actually overstocked. If I were having this problem in that tank I could understand why. I'm at a loss on this one.
Here's a picture of the other tank:
