How do you clean a dirty fish tank?

Answer 1

get a water siphon, an algae scraper and aquarium water conditioner.
With the algae scraper scrub the inside glass and any other areas that have algae visible (the green stuff). If any of your ornaments need cleaning, take them out and scrub them (with something that's new and never use it for anything else) rinse them under tap water. Put them back in your tank.

Then with your water siphon, drain 25% (40% if the water is that dirty) into a bucket. Refill the bucket with tap water and add the water conditioner (this neutralises all the chemicals added in tap water). Pour the water in gently.

And that is how you clean your fish tank.

It needs to be done at least every week

Answer 2

You should do a weekly maintenance which includes using a gravel vacuum to clean any waste or uneaten food from the bottom of the tank until you have removed at least 50% of the water. Also clean the sides of the tank using an algae scrubber.

Then, before adding water back to the tank, first make sure that it's temperature matches the temperature of the water in your tank, and add in the required amount of water conditioner (two common brands are Prime & Amquel+).

You should also have a test kit to test the water on a regular basis to ensure that the ammonia, nitrites and nitrates are at safe levels (0, 0 & under 10 respectively), as well as the PH recommended for your fish; make sure you test your tap water too.

u have to scrup the glass walls in the inside, u have to drain some water in a bucket and put fresh, new water into the tank, change the filter, and much more, you need mediance too, a certain kind of slat, and others which u can get this all at a pet store the people who work there will be happy to answer any of your questions about fishtanks/ YOUR FISHTANK

Answer 4

The best way to keep the water clean is to:

1. Make a water change about every 2-4 weeks. (I would buy an aquarium siphon to get the water out/ and you don't have to drain all the water you just have to take out 50% to 75% of it for it to be effective)

2. Purchase a filter and make sure you change the cartridge as frequently as the directions say.

3. If you wish you could purchase some live plants (they thrive on Nitrates and ammonia which are the chemicals that generally make your tank dirty)

4. You could feed your fish less food or less frequently (This is often times the most common problem since the fish food bottle usually tells you to feed more then needed)

If you still have problems you can always ask a local fish dealer or an employee at any general pet store such as Petco Petsmart or Petsupermarket. ____________________________________________________________ Above answer is correct with these few small additions/edits. First, never completely drain your tank of it's water. If your filter has two pads then alternate cleaning/replacing. Try not to do both at same time. Tanks fresh and salt contain good bacteria to help fight the bad bacteria and breakdown issues in the tank. Removing all the water, especially with a gravel vac, can reset your tanks cycle. Unless in emergency situations never take out more than 50% with 25% bi-weekly being the best. Also, limit the amount of lighting your tank receives. Algae like all plant life need light to flourish as well as nutrients in the water, primarily phosphates. Over feeding can provide these nutrients.

Answer 5

Well to clean water in a fish tank you have to drain out the water by getting a big cup. leave a little bit of water in the fish tank though for the fish. then put clean and good temp. water back in the tank. and if you have some, put a little bit of water conditioner in the tank. Hope this helps!

Answer 6

To clean a dirty fish tank, start by removing the fish and placing them in a separate container with some of their tank water. Then, remove any decorations and plants from the tank. Use an algae scrubber or sponge to clean the interior of the tank, and a gravel vacuum to remove debris from the substrate. Finally, replace the water, decorations, and plants, and reintroduce the fish back into the tank.

Answer 7

The guy at Petco told me if all you fish tank is is infected then bleach it. But if its not wash it with filter water, don't use soap.

Answer 8

If you cant keep a fish tank clean you can buy a fish tank cleaner

Answer 9

Change the water. Leave about a 1/4 of the water in for the nutrients and good bacteria. Also purchase a Plecostomus fish as they eat algae.
