pH Treatments for Tanks

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

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

Took my 1 yr old male cat Bailey to vet for not seeing him pee that much. She inserted him and got some urine (said he had a little crust down there, not sure what she meant but he does sit on litter). Sample showed no crystals or blood but his ph level was 8, which she said could have been from eating 2 hours prior. I know ph should be at least a 6, how can i help get it to that? I did buy some bladder support powder from Mercola pets and i put a small ice cube in his food. Thank you.

Can use mineral water for aquarium. My tap water has lot of heavy metals. I have 10 galloon tank with 4 guppy 4 danio 1 silver dollar. 1silver dollar and 1 pleco died bcoz of 2 gold fish earlier in my tank. So i decided to use RO water. Can i use.

A fellow pet owner suggested Vetoquinol Methigel for my cat who had a history of bladder stones (a calcium stone) 8-10 years ago. Does this work effectively to balance the urinary pH?

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?

After using metronidazole 400mg×2 tablets in 75 litre aquarium tank, my two parrot fish has thread like some seeing near gills and genital area ? How to treat them ?

Hi, My fish has white spot which is expanding. It also has something around mouth. Spot looks white with small dots in it. I thought it is an ich outbreak. Currently tank is treated with Sera omnipur (30% of recommended dose). It is big pufferfish. thanks for your help Nikola

Most people don’t have the money and space to run a quarantine tank. When introducing new fish (without visible ich spots) could I assume that there are ich tomites. Could I do an ich treatment and prevent a full outbreak. ( I have just been through an outbreak and lost all my fish.)

Good Afternoon, I am currently doing some research into how acid burns on animals are treated and if there could be a better way. I was wondering if you could let me know how you currently treat it and also how well does the treatment work. Also what is the most common house hold product to cause an acid burn? , many thanks Mollie

I have a pond in with my water dragon with a activated carbon filter. Is it safe for him to drink? I also used a water conditioner from petco. He is very lethargic and not eating.

I just cleaned my Betta fishes tank I put the same stuff as usual and a couple hours later he started just sitting at the bottom of the tank with his fins clamped together and now he's just sitting at the top and like vibrating his fins then clamping them shut again and I've noticed he lost a lot of his color
