Hi guys,
I'm having trouble with cyanobacteria. I wasn't sure where to post it, but I figured it would be best to post it here.
It's quite a mystery, actually. I have three tanks at home. Two Akvastabil Fusion 100 and one Akvastabil Fusion 130. They are all lighted with two Fluval Aquasky 2.0 LED's (all on the same settings) and filtered with Cristalprofi filters. They are all tinted, as in blackwater tanks. Lots of leaves, lots of wood, not a lot of plants. Except for the two smaller tanks, they're full with floating plants (Pistia). I put the same food in all the tanks, mainly frozen brine shrimp (rinsed in tap water), but I also feed some veggy flakes in the bigger tank, because the fish in there need it in their diet. I routinely add new water to these tanks every week, 100% RO water.
Now, one of the smaller tanks has been developing some small spots with cyanobacteria. I also had a cyanobacteria problem in a previous tank (ugh, the stench was horrible), so it might've stuck on some plants and came into the new tank. The smaller tank had a HUGE phosphate problem, which is one of the reasons I bought a new, bigger tank. I figured that somehow, the same problem had occured in the new tank, as the cyanobacteria came back, but I just tested the water and there's almost no phosphate detectable in the water. Same as in the other, same sized tank. Both tank's no3 were also practically zero. I'm at wits' end at how the bacteria has continued to develop and is slowly spreading around the tank.
Does anyone of you have any clue, why one of two almost identical tanks has developed this issue?
The only one I could think of was perhaps a lack of flow or oxygen, so I turned up the water flow. I hope it helps, but I have my doubts. I'd love to hear your ideas.
Thanks guys,
Jeffrey
