I know this sounds simple but does anyone know of an easy thing to use as a reservoir that can hold at least like 40 gallons? We tried to get a large rubbermaid container but the 30 gallon container could only hold about 15 gallons of water before it seemed like the sides were about to bust open and i didnt wanna push it any further... im also not really tryin to drop $100 on a real reservoir if possible. ive got my whole ebb n flow table set up but i just need a reservoir... someone please help!!
