DIY RO/DI?

[johnnyphish]

Anyone know of a relatively simple way to generate 5-10 gallons of RO/DI water at home each week? I've done a little snooping around and it seems the RO/DI filters are inherently high pressure and require those housings with water lines, etc. Alternatively, how about a cheap, simple, low volume RO unit? Thanks!

I think there are a lot of reefers that only use 5-10 gallons per week.

The only advice I can give is to check Craiglist and Facebook Marketplace to try and score a used system.

I bought a liquegen 75 gpd system off Amazon like 120. I ran it with standard 40 psi water for a while it works fine just slow

The cheapest thing out there is a Buddie RO/DI system. You might also want to consider the following companies Buckeye Hydro, Bulk Reef Supply, Liquagen and AirWaterIce. I too have been studying what to get and can get by with a small unit. However, to spend the additional money, you get standard filters (not limited to one company) and you can also include the use of drinking water as another feature.

Well I think you should get a quality unit.
The RO/DI unit is the front line of your successful hobby.
Today you only need 5 gallons a week, tomorrow could be more.

I recomend at a minimum a 4 stage system.
It will do you just fine and also give you plenty of future expantion for tomorrow.

I have said this many times.
There are things to skimp on and your RO/DI is NOT one of them.

40pis is usually the minimum for rodi units and I think they are rated at 65psi.

here is a write up I recently did on my 5 year old $99 countertop rodi and I make 5-10gals a week. I highly recommeng spending the $20 on a TDS meter to take any guessing out of when to replace the filters.

Reverse Osmosis Revolution 4 Stage RODI Review

I purchased the 75gpd Reverse Osmosis 4 stage Aquarium RODI unit 4 or 5 years ago. It's portable so originally I used to hook it up to my kitchen sink, but my cheap faucet couldn't handle the pressure after a while, so I moved it to the basement, removed the kitchen facet adapter that came...

IMO, if you cannot afford $150 dollars for an RODI system and $100 a year to maintain it then you might be in the wrong hobby. This gets expensive real quick. I have a 55 tall with a 35 custom sump. I have probably 6K in equipment and another 2K in livestock.

Yes, you want to make sure you get a system with standardized filter sizes this way you are able to get filters for years to come.

I bought this 6 stage filter by some company called GeekPure. While their filters cartridges them self suck, the whole setup and the containers are standard size and you can upgrade to nicer filters over time. Maybe look for a cheaper standard rodi unit on amazon, or a used one and add in the relatively low cost filters.
