I am starting the saltwater world. I know nothing about making sumps besides what Ive read and saw people make. So I'm planning on making a sump filter. Here is my plan drawn out. The main tank is 30 gallons. The sump will be 20 gallon. I don't want to use glass for the chamber seperates I want to use something plastic I can remove(but idk what to use any ideas?) I'm wondering if I will need a heater for the sump and the tank or if the one is sump is all i will need heater wise. I dont know what to get for the pumps to run the water bck and out of the tank. I don't want to drill the main tank either So I will use pvc pipe to run the cleaned water to the 30 gallon main tank and out of it. Anymore help on this will be gr8t
