Persistent Cloudy Water
I am running into a persistent cloudy water problem that really has me stumped.
Fish (neon tetras, cories, otos) are doing fine, as a the shrimp and neurites. The tank is heavily planted, and I have cut way back on the food. I do not have an algae issue, either.
I do run the filter at its lowest speed, since it does tend to blast things around.
I do about 15% water change twice a week (10% once, then maybe 20%). I do filter cleans once a month normally (light rinse of sponge and biological media, replace charcoal, clean siphon etc.). I also run a pre filter, which I clean about once a week, since the Fluval plant medium seems to "shed" a little - it mainly seems to collect its brown dust.
I just added some fiber matt, since that worked well, when I was setting up the tank some eight months ago and the media really created cloudiness.
This tank overall has done well, but I like that water clear again! My initial experience was for waiting, but it's easily been three weeks.
Any tips or ideas?
