Hi, so I was wondering what you've used that made a really noticeable impact on improving water clarity. I run UV and the tank does not have any issues. The thing is, its 3ft wide by 6ft long set up peninsula style. So I look right through the widest parts of the tank for viewing. Especially looking down the 6ft length, by say the 4-5' point the water is not super clear. I tried a bit of carbon and it helped for 4 days then back to the usual not perfect deal. I'm considering ROX but previously it seemed to negatively affect my SPS. A rollermat ? What have you found to be good and not affect the corals? Thanks
