I have recently used medication in my 50 gal freshwater fish tank with one 22 year old comet goldfish in it . the meds cured my fish but must have killed my beneficial Bacteria as now my established tank has been going through another nitrogen cycle. It's been four weeks now the ammonia us back to zero so is nitrite zero BUT my nitrates are now spiked about 80 and the water is cloudy. Did 2 partial water changes over the last 8 days. Will a UV sterilizer help ?? Please advise. Thanks Lina

first of all, thanks for your advice with my african dwarf frogs! after the aquarium salt bath they are doing great and even look more vibrant now! i was wanting to know what substrate would be best in the tank. would sand be okay or would they eat that like the gravel? i have a heavily planted aquarium and need something to keep the plants in place but i dont want my frogs to eat it and have something happen to them. i find conflicting information when i research it online. thanks!

Hello, can you help me identify this plant please, the people at the store didn't know the species. Also is my aquarium good

Why is my fish tank cloudy? How can I clear it up? I put some chemical in it but it didn't seem too effective. (Sorry my phones camera is really bad)
