Cloudy Water, Won't Filter Out?

My water has been cloudy for weeks. I left the light off for most of the time hoping it was an algae bloom and it would go away, but nope. The water is green and you can see through it but it is really hard to. It is a 29 gallon BioCube HQI with a modded pump to do 350gph. It has three neon tetras, two pieces of driftwood and a crapload of plants.

It WAS very clear until a few weeks ago when I cleaned the tank up with some aquascaping and I stirred up the sandbed. It got very cloudy and never cleared. I have been changing out filter floss every few days and not much really collcts on the filter floss.

I do have bioballs in the back chambers of the tank and I remember from saltwater that they are a nitrate factory, not sure if that is true for FW, but they are mechanical filtration and I thought that was good.

I haven't fed the tank in weeks and the neons are nomming on the plants... So it isn't getting any added nutrients.

I turned the light back on because I don't want my plants to die, but it still won't clear up.

What could be the cause of this and how can I fix it?

I had something similar and it was a bacterial bloom. If you do a water change and it clears up but is then cloudy again hours or a day later I think that's it. I fixed it with a uv sterilzer , but I think you can wait it out if you're patient and it will remedy itself. Not 100% about that though.

So will a water change help? How long should it usually take?

Water change should fix your problem.

Re: Cloudy Water, Won't Filter Out?

Put some aquarium water into a white container. If the water has a green tint then it is algae bloom (green water), if not, then it is bacterial bloom.

Do a search on both names - tons of info.

If it is bacterial bloom then water changes will make it worse.

Learn what causes each type of bloom and fix the underlining problem. Your tank will be crystal clear in < 3 days.

If 1, 2, or 3 water changes don't help, then get some Seachem Purigen to put into your filter. If that doesn't do the job after a few days, then I'd suggest you need to turn to buying, borrowing, begging, or stealing, a UV sterilizer.
None of these things will fix the root cause of your algea problem, but the Purigen or the UV will certainly clear it up for a while, if not for a long time.

Also, Bioballs are biological filtration, not mechanical.

Re: Cloudy Water, Won't Filter Out?

And you probably shouldn't be changing the filter media so often.

"Nitrate Factory"


Well, do you want it to stay in the ammonia form?

You probably have an ammonia reading from changing the filter floss so often - stop doing that as it's just making the problem worse.

I did some water changes and it is slowly clearing up. Just have to do about a 10 gallon change a day and it is working out pretty well.

Diatom filter.
