Thinking of setting up a FOWOLR

[The Grizz]

My FOWLR does have LR & sand, only because I had it here to use. Take out the gravel ( if you have it in the tank already ) replace with sand, add a few nice pieces of LR to the display & sump, run a good skimmer & forget the bio-balls, they could lead to major issues.

I have not done a WC in my FOWLR since day one, running a SWC 160 skimmer & that's it. Have not tested water at all except for salinity & havent had an issue.
