Hi I have my 72gal bow frt and 30 gal sump up and circulating I have only 1 bag so far of sand in tank ,So I ask ?? What is a good saltwater test kit to get. I thought the kit I had for my fresh also did salt ?? but it did not. I still plan to base rock(transesine type and LR then get a cleaning crew ? What should I get (snails, cleaner shrimp etc ) what type of critters and where and what are my next steps here to do ????
looking for info.

please and thanks
