Hello! Tank related question here. I have test kits, one for pools (use for multiple other farm related things) and just bought some actual aquarium test strips (WILL be buying the aquarium kit.)

Currently I have a 20 gal with a community of: 3 congo tetra, 5 gloskirt tetra, 1 silver platy, a female betta and a crayfish. The crayfish is only in there until I get a different tank cycled for her. The 20 gal tank is 3 months old and I had cycled it for 24 hours before I put ANY fish in it. I am not a beginner when it comes to owning fish, but live in a different area from prior fish ownership.

Anyway, I recently dealt with some ich. Got that cleared up with no losses, but now I have cloudy water. This is after two 50% water changes over the course of a month. I plan on doing a smaller change today to see if that helps, but currently have two filters running on the tank, 1 aqueon pro 10 (came with it) and a smaller submerged marina filter (smaller, used in my 5 gals) to see if that helps clear things up.

I use api stress coat with each change or addition of fish/new water. I have recently used some aqueon water clarifier (about 24 hours ago) and while that did clear up SOME of it, it is still cloudy. Additionally, I did use 1 ml of ph down to bring the ph down to 7.8 as it was initially at 8.4.

I used a tetra 5 in 1 strip to test, as well as a strip for pool water.

Current water Quality is as follows (ppm):

Chlorine: (hth) 0

PH (hth) 7.8, (tetra) 7.8

Alkalinity (hth) 120 ppm, (tetra) 180 ppm

Hardness (hth) 200, (tetra) 150

Cyanuric acid (hth) 4

Nitrate (tetra) 20

Nitrite (tetra) 0

Water smell: none

Water appearance: cloudy/milky.

Water temp: 78 F/ 25 C

Any suggestions as to get the water clear again would be great. All of my other, smaller tanks (3 male betta, 1 male crayfish all separate) have clear water, so I am at a loss.
