15 pounds of it came from my lfs
, i placed that in my sump. Then i found its cheaper to buy base rock online. So i bought like 60+ pounds online.. Ill take a pic of the rock, i forgot which site i got them from. Very pourous rock.
Also, Should i scrape off that bleached corraline in the back or let it be?
-by the way all my livestock are in my 17 gallon bowfront. So i wont harm anything moving these rocks around. After i scape it, the fish will be moved back in. I changed all my water to ro di
, so my fish havent been in this tank for about 4 months, its fully cycled now though.
