Hi everyone I'm back ato trying to do a reef tank.. i had a 20g long sitting around and wanted to do something small that I can do with my kids.. I recently had a 120g reef last year which wasn't really a success cause everything got more expensive and with a little one it just got harder.. so far I got a tank and a wp10 wavemaker and heater.. also got a aquaclear 30 that I had bought justhe collecting dust.. I will be using red Sea pro salt.. any advice and helpful tips would be great
