Angry Cloudy!

Hello everyone!
One of my tanks is a 20 gallon community tank. it has been set up for over a year ith no issues. All of a sudden the tank is clougy (white). The neighbor was feeding them while we were on vacation so i am sure they were over fed. When i test my water everything is pretty much spot on, nitrates are a little high. I do water changes on both tanks every other week. I did one on sunday and one on tuesday this week. ANyone know how i can get my tank clear again? HELP!!!

What I can tell is that I would not use any chemical treatment to fix this problem. You most likely have 1 of two things, a bacteria bloom or a precipitate caused by a pH change. Was the water cloudy when you returned, or a short time after? Did your friend give you any information on the timing of when the tank became cloudy?

How weird, mine is doing the same thing! I've been doing water changes every 3 days or so, but nothing seems to help. I will be watching this thread for sure!

{Britny- I would suggest that you start a new thread. You will probably get more help! - Pasfur}

I just realized this might not be in the right forum. Is this a saltwater or freshwater aquarium?

This is a fresh water set up. I reentered it below but still no luck. Lots of views but no suggestions.

These questions still apply. Give some more information and we can help.

The water was cloudy when we got back. I did not want to ask them about when it may have turned in fear that would feel bad. Never know when I am going to need pet sitters again . It looks like it is starting to clear up some. 3 water changes this week (about 20% each). Hope this helps. Also FYI, the tank is a little crowded
8 danio's
1 gram
2 bottom feeder (weird snout)
1 angel fish
1 X-ray
2 tiger barbs
1 frog
And some sort of red barb thing

I have good filtration. Fluval 3 stage 70 that hangs on the back with the bio/charcoal/sponge. The filter is suppose to be for a 60 gallon.

There are a couple of possibilities. The most obvious is that the tank is overstocked, and although it has worked just fine so far, as these fish begin to grow and mature, they will produce more waste. Combine this delicate balance with some overfeeding while you were on vacation, and you probably just had a bacteria bloom.

Another option would be related to the cleaning of the filter. A lot of people clean their filters just before leaving town to make sure everything is "read to go" with the tank. Unfortunately, if they clean all stages of the filter, including the sponge filter, they are often harming a large supply of beneficial bacteria. This again could lead to the cloudy water situation.

I'm glad to hear things are settling down. Most often it is just a matter of patience. I would, however, strongly suggest that you thin that tank down. I would personally begin by removing the Tiger Barbs.

I concur with all of Pasfur's advice.

This tank need more frequent water changes than alternate weeks (the original schedule). Every week, changing 50% (half) the water is the absolute minimum with this particular fish load. And here I refer to not only the number but the species.

On that, you have fish that are not "compatible". Please read the info in our fish profiles, second tab from the left in the blue bar at the top, or you can click on the fish name when it is shaded in posts [it will shade if it is identical to the name in the profile, scientific or common]. As, Pterophyllum scalare for the angelfish, or Tiger Barb for that species.

You need to separate some of these fish somehow for their own health. Stress will be high as it is, and you will understand why from the profiles. But any questions, ask.
