Predator tank

Any suggestions on how much rock to put in the tank for 150 gallon. I ordered a marbled cat shark from Bruce at fishy business and if it don't come I guess it's time to go to the critter to get one and hopefully a ray also

Is it strictly a FOWLR Pred tank? I guess it depends on the filtration you choose and how often you plan on doing wc's

Yea no coral I have a all glass model 4 sump and a great skimmer water changes will be done 2 times a month with a 30 gallon change each time

I would guess at least 85lbs or more. Maybe even a fuge in your sump area.
