Well wee Update , wasn’t fully happy with the way my diy rock turned out in the end I was out about $50 , good cool experience and would do it again but it was taking to long for my ph to drop and I got lazy after the 3rd month of wc on the 1st cycle of the man made rock,
Ended up ordering 75 pounds of 2 different Marco dry rock (flat on one side , and the flat on both sides) and some premium Marco shelf rock from reefsuplies,
The sump needed cleaning bad , gave it 2 good cleans and in a vinegar soak out back now .
While the sump was out , i wasn’t thrilled with the dark stain inside the sump made it to dark and dingy lol .. so painted it and much happy with it !
Next will be waiting for the rock to show up and get the sump back in and start plumbing !
