I posted phosphates to high and was told my 40# of non porus dry rock was most likely it. Removed all 40 pounds yesterday. Did vinegar test on all and no foaming. Wife said it looked like the rocks we used to step on crossing a creek in Indiana. marcorocks.com was suggested in that thread but out of stock on everything. Looking to buy 30 or 40 pounds of rock. Actual life rock with coraline and full of critters which used to be the norm at LFS 12 years ago would be nice. Of course $2.50 a pound then and no shipping
Been looking at florida aquaculture rock.
Thanks in advance,
Gary Porter
