also i'd like to know if y'all can help me figure out why in the

my water is sooooo cloudy
-I don't have test kits, so i took some water to the store. She didn't give me actual #'s, but what she said is:
- the ph is a little bit low
- there is a little bit of ammonia in the water (but she said it shouldn't be enough to cause cloudiness)
- she did the nitrite test and she said the test water stayed yellow, which meant the levels are good...
ok, so here goes:
30 gallon tank, set up for about 2 months
2 fantails, each about 5 or 6 inches long
not showing any signs of stress or sickness
water changes once a week, about 30%
2 bubble walls
penguin bio wheel 330 filter
aquarium salt and water conditioner are used
-i added some of the stress enzyme on friday......the water got horribe looking, so i changed some of it today; and I tried some "algae fix" because there seems to be some water borne algae in there, and it completely cleared my 10 gallon betta tank...but it didn't make any difference in this tank, the water is still horrible looking......it is so cloudy that i can barely even see the bubble wall or the filter uptake pipe in the back :crp
-i'm so frusterated, i don't know what to do...i am about to just empty the whole tank and start over again :angry:
