I just bought a 47 gallon column fish tank, now I know that wet/dry filters are used for salt water tanks, however I’m using my tank for cold water fancy tosakin goldfish. I heard that wet/dry filters are the best, even better than canister filters and if you build it yourself it is much cheaper. I am wondering should (and CAN I) build a wet/dry for my tank or should I go ahead and shell out 200+ dollars for an Eheim 100+ gallon canister filter?

I recently moved into a new house and there was a pond in the garden. The water was very green with goldfish in it. I could only see them when they came up to eat.
They are water lilies and other aquatic plants.
I have bought a pump with filter, biologic filters and UV lamp. Now the water isn’t green any more and I can see the fish when they are near the surface but the water is still cloudy and I can’t see them any more when they dive. It has a grey colour and it looks like there is a lot of durt in it. I have tried to change the water: I used the pump to put water in the drain and replace it with clear water.
It is still the same.
I don’t think that the pump and filters are doing anything now, as for the last 10 days I haven’t had to clean the filters: the water flows normally out of the fountain.
What can I do to get clear water?!!
Thanks.
Nikki

I know that usually a tank has to be set up for three days before you can put in goldfish but how much longer than that should I wait if I accidentally added five times the amount of tap water conditioner.
I haven’t bought the fish yet

I love having the tank in my room but I just canNOT sleep with that running water sound! It’s a 10 gallon tank with 1 goldfish and 1 algae eater. I just want to know if it is safe to turn off their filter when I go to bed and turn it back on in the morning.

I got a goldfish from a carnival & it’s already in it’s tank, but I’m just wondering if filling it’s tank with the water from a Poland Spring water bottle is OK. I know I need to take out just 1/4 of the water every week. But is it OK to fill that missing 1/4 of the tank water with Poland Spring water?
Also, I have googled about it since yesterday (I try to find the answer myself before asking of course), but have found no sufficient answer, so that’s why I’m here, asking this.

Right now in my Science class, we’re doing a lab on how the water temperature affects the cellular respiration rate of goldfish. My hypothesis is that as the water temperature increases, the cellular respiration rate will increase. Is there a good reason for this? I mean, we need to know some background information or scientific concepts supporting our hypothesis, and I wasn’t sure what to say. Why does the respiration rate increase as the temperature increases? Does it have something to do with how fish are cold-blooded?

I moved to a new town and set up my long successful freshwater aquarium with tetra fish. I had a very hard time getting the water chemicals to balance and they pet shop finally told me that the water where I live is really not workable for aquariums because of the chemicals. All of the fish died, despite my experienced efforts.

We have a goldfish that we just use spring water for in a bowl and he is nearly 5 years old! So, I know spring water is ok for that type of fish.

Does anyone know that if I start with spring water and work from there, would it be ok for tetras? Would I even need chemicals??

I got him about two weeks ago, and put him in the tank with another goldfish of the same species. They seemed perfectly content with eachother. I used water from my Pur filter for their aquarium. I just looked in the tank about thirty minutes ago, and I saw him lying on his side at the botttom of the tank. He wasn’t floating, and his eyes weren’t glazed, so I don’t think he’s dead.
What could be wrong?? My other fish seems fine, but I did get him a day after Mystery (the fish that’s lying down) PLEASE HELP!!!
I don’t see any movement from him at all. I don’t think he’s breathing, but I don’t know. There’s no filter in the tank, just a bubbler in which to put oxygen in the water. Remember, I used a PUR water pitcher filter to filter the water and use it in my tank.
OH, and I cleaned the tank two weeks ago. The goldfish are pretty small, and my mom says if I clean the tank toomuch it’ll cause them to go into shock.

Hello all. I own a fresh water aquarium with a little goldfish in it. I need to replace the water because it is fairly dirty. However, I left tap water out before I emptied the tank, much to my dismay, the cleaning lady threw out the water thinking it was uninportant. I need to re-fill the aquarium, but only have Dasani bottled water on hand. Can I use that? If not, what can I use? I cannot go out to purchase anything.
Thank you so much in advance =)
Thank you all for your help. I did use Dasani and my fish is swimming around happily, apparently with no problem, so that’s good. no signs of dying or having a disease.

I recently cleaned out and changed the water in our goldfish tank. Normally I use spring water in the tank, but last night I filled it with city tap water. I had heard that if that water is left to sit for about 24 hours before the fish are added that the chlorine will be gone enough to be safe for the fish. Is this true? How lond should I wait until I put the goldfish back in?

I have a tank that has cycled. It’s 14 gal and had it for about 3 months or longer. I think I have a bacterial bloom as the water is a bit cloudy. I have kept up my weekly routine of cleanings and routine feedings. I only have a little goldfish and a blind cave fish in it. I know it isn’t the rocks, and I siphon out from the bottom. I changed about 35% of the water yesterday. I have read that this is normal and that it usually settles down, but it’s still going on for 2 weeks now. Fish and water parameters are fine. Should I up the water changes? Filter has also been untouched.
Thanks!

I have a goldfish and when doing partial water changes, I only use (bottled) spring water. I never use water purifier because I assume the water is already pure and free of chemicals.
Should I buy distilled water instead of spring water? It is hard to be precise with water purifier because my aquarium is only 6.5 gallons and has one goldfish…
