I've been running my tank for close to 9 months now.
everything is fine.
dosing ada fertilizers according to their instructions...
I change 50% water every week religiously. Is there any reason why I would start to grow diatoms close to end of week?
Once I scrub the tank and change water on Sunday, it'll be fine until around Thursday, then diatoms start to grow on the side of glass.
any suggestions???? i've tried to shorter the length of light & reduce fertilizers, still same.
