I have posted about this before. Tank cloudiness due to high particulate concentrations is common when changing substrates or adding substrate for the first time. It is also an easy problem to solve. To do so you have a few options, listed below in no certain order. NOTE: It’s worth mentioning that cloudiness due to bacterial blooms and such require a different solution. That’s a post for another day.
- Let your existing filter(s) do the work
- Add a new, temporary mechanical filter
- Do nothing and wait for the particulates to settle
