I have a 40G FOWLR tank. Right now, it contains 1xClown, 1xChromis, 2xRed Leg Hermit Crab, 2xBlue Leg Hermit Crab. I will add 1 more clown, and either 1 or 2 Chromis. That will probably be all the livestock in there. My water changes are not that big, however, I want to invest into RO/DI unit. My tank will eventually be upgraded to 90 or 120 gallon unit in the future. I'm not sure which one to go with: SpectraPure or BRS (4 or 5 stage plus). I have read somewhere you want to have 4:1 waste ratio as it extends the live of membrane and DI filter. Can you guys give me some pointers and/or recommend unit? Thanks.
 
Get the most stages you can afford. A 5 stage would be cool. Also get an inline TDS meter. Put the IN probe upstream of your DI resin and the OUT probe downstream of it. That way you can see when its time to change your resin. BRS is your best bet IMO.
 
Check out buckeyefieldsupply.com they have some really nice units for less than you'd expect. Big barnacles got his from there and loves it.
