I bought two bulk tanks in the last year during the off season. The 250 gallon cost me $200 and the 375 gallon cost $300 i.e. $.80/gallon. Got lucky I guess. Non-working of course. Also, I got some great advice from the community on the trader. I was going to get one large tank and was advised to go to two smaller tanks for my size operation so that if I ever increased in size, I would have one tank for RO concentrate and could clean one tank while the other is being used. This year, my year was so poor I only used the 375 gallon tank, but glad to have the 250. I know it will get used.
