large 55 gallon drums. theyre drilled at bottom for top off. if you ever thought about setting up an auto ro/di bullet proof top off here's your chance. I'll give you everything you need. Its completely gravity fed and doesn't require top off switches which can fail. go for the tried and true method. If you have a fish room or remote sump this is an awesome option! these things cost a ton to ship and have them ready for you no shipping required. have 3 in total. can use for mixing salt water as well. these retail for $75 piece plus hefty shipping cost. bought brand new and only stored ro/di water. they reefsafe food grade high quality. $30 a piece. Buy all 3 for $80. Will include a gravity fed auto top off if you buy all 3. Otherwise gravity fed auto top off and included plumbing is $15.
