I have recently being using a little deionised water in my shrimp tank to reduce my GH and TDS in an attempt to get my colony breeding.
Tank is only 22l and if I am doing a 15% weekly change with 20-30% RO then I only need a small amount each week.
What I am trying to figure out is if I keep this up whether it is worth getting an RO unit? LFS doesn't sell RO (a few do a bit further away but that becomes a pain) and the deionised water was £1 for 2.5l in Tesco so would take some to make an RO unit cost effective.
In terms of RO is there much of a difference in quality? I see some unbranded units being much much cheaper than the named ones but is this because they are much much worse?
Will an RO unit actually do its job for small amounts or do you need to run a decent volume though it?
Finally what about upkeep? How often do you need to replace membranes etc?
