Hey guys! Just setting up my first reef tank and have borrowed a friends salinity test but had to give it back, foes anyone have one they are wiling to part with or can sell for cheap that would be great. I also need a canister filter and might wait until next week. BUT if anyone has one they are no longer using OR will sell gfor a good price, let me know!
