I have a 90 gallon with two fish in right now. The substrate is a sand. I have a few rocks and two pieces of driftwood that have been in the tank ever since. Some people told me to get rid of the driftwood. I took two pieces out and put them in a smaller tank. That tank is still clear as hell. I don't think it is the wood.

I had this tank setup in another house where it was always clean. I've gone through many types of inhabitants (Amphilophus, Royal panaque, Crenicichla, Hoplias, etc...). I moved it to my house almost two years ago. Since I've moved it, I've been fighting with some serious cloudy water.

Right now, the current inhabitants are a 5-6 inch Trachycorystes trachycorystes that is fed once every few days (as he stays in the wood and doesn't come out), and a 6-7 inch Parachromis dovii who is fed a few pellets a day. I would not consider him overfed. He will be moved into a larger tank in the not-so-distant future so I don't need to be hassled on him being in a 90. Please help me with the tank.

I've had an XP3 and an AC70 running on this tank for the last two years as well. Originally, it had two AC70 and was crystal clear. I took one out and added the XP3 and it's been cloudy ever since.

The XP3 has two trays of biomax and the bottom tray has the stock foam. The AC70 has foam, carbon, and biomax.

I've used Seachem Clarity and Stability. In fact, I've used several "clarity" products. The water is treated with Prime during water changes.

The water is just... cloudy. There is no real color. Just murky. It's not green, red, blue, purple, mauve, or anything. I've been told it's a "bacterial bloom" and have done everything there is to treat said bloom.

I've taken my fish out and have done full water changes. I wash the biomax with tank water only. I fill the filters with tank water. My water changes are roughly a week to two weeks apart depending on how busy I am, or how much I've fed the fish. The filters get cleaned every two-three weeks.

With two fish that are not fed very much, I don't know what could possibly cause this. This tank used to be considered a show tank to me, but now I don't even like turning the light on. Considering the tank has been here for two years, I know there is sufficient bacteria needed. I am completely stumped and don't know what else to do. Should I add another filter?

(For the record, I've been keeping fish for years now. At present I only have two tanks set up and the other one is perfect and is over-stocked... I took old decor from the 90 and put it in that tank)
 
I had an unfortunate event and cracked my 29gallon tank. That's when I had the same problem as you for about 6-7 months... I even tried that Purigen stuff that people on here rave about, didn't help. Then one day it was like magic, clear, crispy water...

I did nothing to the tank that I wasn't already doing... Weekly 30% or so water changes, rinsed filter media once a month. It just sort of cleared up on it's own. Weirdest thing...

I felt just like you too. I hated turning on the light. Now I hardly turn it off, and the water is STILL clear.
 
My tank went through a similar, hazy-milky white period.
All said it was a bacterial bloom that would resolve itself in a short time period.
Never happened.
Waited well over two months with no improvement.
Lucked into a very good price for a nine watt UV unit.
Plumbed it up. Hung it in my sump and forty eight hours later, the water was crystal clear. Crystal clear is a term used allot, but I swear it was the clearest water I had ever seen in a fish tank.
I never did find out the cause of my water problem, but I did find what worked for me.
 
im having the same sort of prob. except mine is a 120 w. an xp4. its a fairly new tank and i have a few small fish in it, so i think its still cycling, but ive tried every water treatment there is. just yesterday i put to 12" bubble wands. that seemed to help (at least the film at the top of the tank is gone). i got my xp4 from an lfs that was going out of business for aroudn $150, although it was a good deal, im starting to wonder if its junk. now hearing your water has been cloudy since you got your xp3 running makes me really scared.
 
Bacteria bloom typically last for a very short period...odd that your tank is still cloudy...I too had a Bbloom over night about 2-3 weeks ago in my 450gal tank...very cloudy and then when I hooked up my 50watt UV, the water cleared up within 48hours, clearer then before....so try a uv sterilizer...seems to work over chems.
 
What sort of wattage should I look for?

I can get a Grech Submersible 9 watt UV Sterilizer for $30. Or, for an additional $10-$15 I can get a Odyssea UV 18 Ultraviolet Sterilizer. The latter sounds like a pretty good deal to me.

I could get one that's 60 watts, but it looks pretty big and is recommended for koi ponds!

All of these are used on eBay and are from reputable sellers. I would prefer buying a used one as I am in between jobs and need to buy bike parts, too!
 
i use a rena xp2 and a 350 magnum cartridge filter and i have some of the best looking water i've ever seen in a fish tank...have to swap out cartridges in the magnum every 3 to 4 days but its worth it(just clean the old ones)
 
Go for the 18w. It seems very very cheap! Too cheap to be real!

Are you sure that's not the price Judy for the bulb? Most will run over $100 for a 5-6 watt version.
 
If you get a UV, make sure it is complete.
There are many that sell the UV only and it needs a pump for use.
