Hello, I have a long term problem with filamentous diatoms, they appeared shortly after cycling my tank. People on FB groups confirmed it is 100% FD but no advice worked so I'm trying here. My water parameters: ph 7.1 ammonia 0, nitrite 0, nitrates 5-10. I have RO water that I partially mix with tap water. I tried everything from daily 50% water changes to reducing lights to enhancing my filter to introducing a crew of amano shrimps. It is just worse and worse every day, my plants are not visible if I don't manually remove it. My tank is heavily planted and plants seem very healthy and growing despite that. To clarify it is practically only on moss, other plants are almost fine, it is just so bad on moss that it is literally everywhere in the tank if it makes sense. 70l tank, co2 24/7 with autocontroller and bazooka diffuser, temperature 24C, superfish 28W light 5.5 hours a day, external canister filter and good water flow. Does anyone have any idea what to do? I'm at the point of regretting getting a tank, it is a pain to look at it. Feel free to ask for any additional info and thanks.
