You could try running some carbon that might help.

i borrowed afilter from my FW tank to help with the clouds. alot of cleaning lthe filter floss nessisary but did a fine job.

I just got an attachment that goes onto my powerhead which has that floss in it and its startingto clear up. The LFS said that it could be like powder sand from my substrate.

I apparently now have an algae bloom aswell (water is starting to look green)

Besides a UV sterilizer how to I get rid of these?

- Water changes
- Reduced photoperiod
- Skimming

Have you been able to get a picture yet? As they say a pictures speaks a thousand words.

It is defitnitly debris from your substrate IMO.
I rinsed my sand for 3 hours before i put in tank still had clouds. took 2 days and 2 filters to get rid of it.

As for the algae if you dont have any livestock yet turn the lights out for most of the day for a couple days.

Have been stiring up your snd to get all debris out? if sou this would make your various levels go all over the map thus creating a algae spike.

I find that a UV sterilizer helps reduce algea as well.
