I bought my daughter this fish tank. It is a 50 gallon tank. She loves fish. I have bought everything under the sun and the water is still cloudy. I cant get the water to clear unless I take most of the water out and then it is only for a day or to. I put water conditioner and alge cleaner in it. It is still cloudy. Some guy at petco sold me this stuff for $15 dollars and it still cloudy. How do I get it to clear up? I must be buying the wrong stuff.

Around here there is a shop dedicated to fish and fish tanks... not your average pet store, but a store that specializes in fish and tanks... If you bring them a water sample they can test it and see what it's missing and tell you what you need to clear the water. Are you using a filter with a sponge and carbon? I remember when we would first change our water it would be cloudy for a couple days, but eventually the filter with the sponge and carbon would clear it out.

I has a filter system on it. I am wondering if I need two of them with such a big tank. It's filter system has those sponge carbon cartridges. That is a good idea to take some of the water to the pet store and show them. I might have to do that. We have had it for a month and It stays clear the first day I change the water then after gets cloudy again.

Your filter should say what size tank it's meant for, so long as it's 50 gallons or more it should be fine. Another problem.. are you using tap water conditioner, and the right amount? If you're filling the tank with tap water, you need a conditioner to remove some of the stuff in the water, and there is a specific amount, like 5 drops per gallon. Anytime you add more water to the tank you need to add more of this. We used to fill our tank with a gallon jug, and put 5 drops of the conditioner right in the jug before we dumped it in the tank.

Do you have a filtering system in the tank? If you don't have something to filter out the fish poo and keep things aerated, you're going to have a cloudy tank, regardless of what chemicals you add. You also will probably have to 'vacuum' the bottom of the tank to get the old food, fish poo, and whatever else settles. They look like little siphons and you just suck the gunk (and a bit of water) into a bucket.

Syphoning the tank doesn't need to be done often, every couple months or so, and it should only be a quarter of the water each time. Buying bottom feeders can help so you don't have to do it frequently, like cat fish and sharks. The filters usually have sponge and carbon, and these need to be changed probably on a monthly or bi-weekly basis, but you don't want to change the sponge and carbon at the same time. You need to leave some of the bacteria in the tank.

I has a filter system on it. I will try that vaccum thing and see if that helps.

We have a pretty big tank, too, and changed fish food! It cleared up within a few days! Try Wardley's Essentials Tropical Fish Flakes. It's in a can with a blue top. We tried all kinds of things, and the food did the trick. Good luck! Let me know if it works for you, if you can!

Hello honeydew, I had the same problem a few months ago. The fish store sold me a bottle of liquid which I honestly don't know what's in it. But after a few drops it made the aquarium really clean. It took some time though almost half a day. If the stuff you bought doesn't work then you should return it to the store and get your money back. Perhaps the water you put in is dirty? Try using filtered water. Or if there is sand or stones in the aquarium, clean those first. :)

I suggest you get a filter system and make sure your water is not hard water. Mineral deposits in the water could make it look cloudy.

do u have salt water or fresh? I run salt water tanks and on my 30 gallon alone there is a mini protein skimmer, and 2 filters. If you have just started your tank than it may be cloudy until the levels are normal

If you're using a filtration system that should help. If it doesn't, then you could have several problems. First, are you treating your water with a product to remove chlorine and other heavy metals from the water? Are any of your fish showing any signs of being sick? Cloudy water could also mean a buildup of nitrates or nitrites in your water. Have you tried buying an aquarium testing kit? If not, test your water and see if it reads anything bad in your water that shouldn't be there. If your fish are sick, you'll need to treat your fish and the tank. If they're not sick, you may just have to cycle your tank for about a week, sans the fish to restore a balance without the fish. Then, use a fishnet to put the fish back into the tank making sure not to put any of their old water into the tank.

We had that problem with our 30 gallon hexagon aquarium and after it was cloudy it started turning green. Well, PetSmart told me to bring in a water sample but it was so bad I ended up emptying it completely out and starting all over. An all day job! Whew but it is so clear now! Another thing, have you tried the drops that promise to make it clear? They didn't work in our case but they might in yours. Hope you get it cleared up and God bless you!

I wish I could help you here, but I am sorry I can't. I just love fish tanks and fish and spend a long time admiring them. But I don't own a fish tank. One day, I plan to have a beautiful aquarium. I wish your daughter lots of luck with the fish tank. What fish are you planning to keep in it? Cheers and happy mylotting

Some also forget that an aquarium has to run a week on its stystem without any fishes, so the biological system like bacteria has a chance to grow. The fishes produce fertilizer and the bacteria system needs time to regulate it. This is also one reason why you shouldn`t clean your filter too often and if you do not all compartments same time.

Hello honeydew We have 2 big fish tanks in the house , actually it is my husbands hobby, i really don't know much about the fishes because we have more then 100 fishes and my husband buys filters and cleaning stuffs from petsmart, he cleans them almost every 10 days vacuuming the bottom emptying the half of the tank and filling them again and adding some vitamins and moisturizing products to keep them clean. You can go ahead and check some internet sites to get good advises about keeping the tanks clean, have a great day!!!

When the water in my fish tank is cloudy I take these steps: First, I put some drops of this clear away stuff that makes all the floating stuff coagulate and get sucked up into the filter, Then, I change the filter Also, I use these no more algae tablets that evaporates any floating algae in the water that is making it look cloudy. If none of that works (I haven't experienced that yet) Then I would change 1/3 of the water, and while that WOULD make it cloudy because I'd be stirring up rocks and stuff, I would wait for it to settle and see if it cure my cloudy water. good luck to you!
