It's been 10 years and I'm slowly getting back into the hobby again. I am currently working on a 220g drilled aquarium with a 75g sump. I installed baffles for my heaters, mechanical and biological filtration compartments and sealed off about 15 gallons that I am going to use for my automatic top off system. I'm also considering setting up an additional 55 gallon supply storage tank as that I will be using for handsfree water changes (I'm tired of carrying damn buckets)
What would be the best way to supply fresh water to my 55 and 15 gallon reservoirs? Im looking at a 600 gpd RO system. But the more I try to read up on this for answers, people are talking about using RODI systems. I know DI is highly recommended for saltwater, but would it be necessary for a FW setup? I have soft tap water with neutral ph

I would use RO unless its an elaborate planted tank and you are dosing ferts / minerals precisely.

As for supply, first off what ever your RO unit feeds into needs a float valve / shutoff. If not, you will forget its on and flood the room... multiple times. For big systems I used Brute trash cans and the wheel base, easy to drill for the float and move around to pump water into other things. I wouldnt suggest cheap trash cans or plastics as they can leech bad things, never had probs with the grey brute ones. For topping off your tank, I used an ATO controller with 2 mag switches and a small powerhead.

Thanks for the info!. I purchased both the tunze 3155 and 8555 systems for this set up, and yes I'm going to use a trash can instead of the divided part of my sump. I was going to get a brute but I ended getting Carlisle can that saved me a couple dollars. It is stamped food grade by the handle. So I'm hoping no problems there, I'm going to have to keep an eye on it.
