Im starting my new 50 gallon + sump next weekend . I thought about putting the sand in the bottom and then filling with RO
then adding the salt and letting it all mix up in the tank for a few days before getting my new live rock from the lfs
shop . Ordered . Everything will be new . Tanks , skimmer , pumps , uv
light , RO
unit etc . This will be the first time ive made my own water? . Ive not yet got any salt. Any recommendations . Is my plan ok or have I to think again.
