Fluval CO2 Aqarium Kits, Systems & Accessories

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

I got a new betta in January, and I'm starting to notice that his tail is fraying a bit. I'm concerned because I have another betta, and his tail is really frayed too, but I thought that maybe he was always like that. But I definitely know that the new bettas fins were not. I have a heater and the chemicals are fine, and I use melafix fish first aid every time I change the water. The first pic is what he looked like before, the next is what he looks like now, and the third one is my other fish.

My 55 gallon fish tank has hard water how do i clean it out that won't harm fish?

I noticed bloat in my flowerhorn about two weeks ago. It was there when I fed him and went away when I didn't. So I treated him with Epsom salt soaked pellets, bloat was present then. Then I noticed white poop so I stopped feeding entirely and added metronidazole 400 to the tank. Didn't work as I only saw white poop, so I added the medication into his food and now I can see brown poop hanging from a clear poop sticking out of his butt. Earlier the poop didn't stick out of his butt. What to do?

My flat-coat has had liquid B.M.'s for the last 7-10 days. My vet has prescribed Proviable-Forte, a digestive health supplement. He is showing no improvement after 2 days. He still has a good appetite but throws up any little bit of chicken meat that I give him to help him eat the paste. He seems to keep his kibble down but drinks lots of water. I am thinking he may have an obstruction but not sure how to proceed.
