HAPPY to find this forum, and hoping to find an answer to a problem I've never had in all the years I've been an aquarium person.
My current one is a lazy one,....a 15-gallon tall tank with only 4 goldfish and a plecostomus, although 've had years of experience with tropical fish and larger tanks.
The tank is Top Fin, as well as the filter. We've had it about 6 years. We change the filter packs regularly, with no problems. This last time, we changed the filter pack, and within 2 days the water was cloudy. No change in food or temperature. Treated the water with "Brite N' Clear", and it helped for a day, then back to cloudy (no color, just cloudy). Changed out about 25% of the water, then it went cloudy again.
Bought a new Top Fin filter with a new filter pack...no change...still cloudy.
Changed out the entire tank water, rinsed the gravel (the original gravel), treated the water with "Start Right", let it sit a couple days with the filter running, rinsed but didn't scrub the plastic plants, to save the bio process, and it was clear again....for about 2 days, then it cloudied back up.
Now what do I do?
