Need some help here..
I have a 2 x 1 x1 frag tank connected to my 4 x 3 x 2 main tank. i.e. water from main tank will flow into the frag tank and then out into the common sump.
Problem is my frag tank is facing some cynobacteria.. while my main tank is running good and perfectly clear from it.. So it shouldn't be due to the quality of water.I dont have much LS in my frag tank too.. 4 fishes in it..
Is it due to too much light?? currently running on 4 x 24 watts T5 Or
Too little flow ? Currently with a Hydor 2 wavemaker and flow from inlet pipe.. Or..
All algae is diverted and grow in my frag tank just like the principle of an algae scrubber??
Any idea to solve the problem?
