What RO/DI system do I need?

[KyleC]

Hi all, considering purchasing an RO/DI system. I have an aqua one aquareef, 300 litres with approx 40 litre sump. Is a 5 stage RO/DI system overkill? Would a 3 stage be alright? Looking something affordable and practical. Ideally one that can be hooked up when needed and packed away after, something compact. Is it cheaper to replace cartridges, are there systems in where you only replace the fillings? Any advice appreciated.

3 stage units usually are missing the DI resin cartridge which will produce only RO water and you wouldn’t get 0 TDS out of it. If you want a small compact unit that can be packed check the aquatic life RO buddy, I have it for my reefer 250 and it is enough for my needs. however, with this you will need to replace the cartridges as a whole. If you go with a standard RODI unit like the BRS one you would be able to replace the fillings which is cheaper.

Thanks! Yea, looking for one where I can replace the fillings to keep the costs down long term. I'll check them out

Would something like this work? It's by Glamorca, and while it's 5 stage, it's nice and compact. I'm pleased with it.

I just purchased the RO Buddy, it is nice and compact but I think I'm going to return it and get something a bit nicer. Feel like I'm going to regret not going that route to begin with

That does looks nice and compact! Someone local reached out and offered to sell me their osmotic 5 stage rodi system (100gpd) for £60... seems a fair deal, not as nice as this but as long as I can pack it away after then it'll do the job.

That's a great price on a 5 stage!!

Be sure to replace all filters/ro membrain and flush lines after!! Great deal!

Happy days, wasn't too sure if it was good or not. Comes with spare DI resin and inline TDS also. A couple months left on the filters and membrane should be good until August.
