Hi! Not sure why, but our 20gl tank has been doing well for 3 months. Then I decided to add a substrate and 10 plants. Fish still did well with all this change, plants growing as they should, water changes at 20% about every 2 weeks or as needed. Added 5 nerite snails, 4 amano shrimp, a couple of ghost shrimp. Water was clear. Then added a few more colorful plants that needed a CO2 booster, Plant fertilizer. Our water was so cloudy after 2 days you couldn't see the plants in back. So no fish, shrimp, snails lost (knock on wood) The levels are all within range, and 0 ammonia. But still cloudy. I did a 30% change yesterday and it did get a little clearer after a day. My numbers are all within range. When I change the filter I make sure to let the old filter drain water to new filter and submerge in the tank prior to adding to my Tetra whisper 20-40gl tnk filter. lights are timed for various times of day and turn off at night. What am I doing wrong?

As long as your parameters are kay and the livestock is doing well, it's most likely a bacterial bloom that needs to pass on it's own. Stop doing the water changes for now because they are making it worse, not better.
As for the filter, the nitrifying microbes are on the surface of the filters not in the water so the only thing you should do with them is lightly rinse them off so that water can pass through them. No need to replace them until they are basically falling apart and before they hit that stage, you want to add a new filter while the old one is still in the filter box so that the nitrifying microbes can migrate to the new filter.

Hope this helps. (y)
