RO/DI Purchase Questions

[cjqsmom]

I am ready to purchase a RO/DI system and I am not sure what the best one is.

Currentally I am running 2 tanks a 100 gallon reef with 30ish sump and a 90 fowlr with 20ish sump. We are looking at getting a 20 gallon QT to run with the reef when its not used as a QT, knowing that at times we will have to drain it should we need to add medications if needed.

What size should I get and brand.
I was looking at the SpectraPure MaxCap RO/DI System, 180gpd w/ Pressure Gauge & Purity Monitor for $430

OR THE 90 gpd for 370

On the above two I was looking for replacement filters and only found 3 packs not 4 is that a problem?

or the SpectraPure CSP-DI 180 GPD RO/DI System for $400.

or The Typhoon III Extreme 150gpd system made by air water ice $270

Does anyone have any experience with these or should I find a different one.

Any comments or concerns would be appricated.

I got the basic Typhoon III (5-stage) 75gpd for ~$160.
To me, thats good enough. Its not like you need to change water everyday so 75gpd is more than enough. I always have about 30-40g salt & 10g fresh RO for top offs on hand at all times.

I'm probably over simplifying this but RO/DI is RO/DI...don't go cheap but is there any real extra bang for spending 400+ on a system? Rather spend it on fishes.

MaxCap is the best. IMO the 180 GPD is worth the extra $50-$60 bucks since the hand selected membranes on their own run around $95.

For replacement filters you'll want to change the sediment and carbon block every 4-6 months. The first DI should be changed when the output is around 6 TDS I believe, but you may want to post on the Spectrapure forum on RC. For the final DI replace it when the reading is anything over 0 which should be at least one year.

Oh.. for the 180 GPD, you'll need at least 65 PSI. Usually not a problem but worth measuring the pressure.

I was looking at that one too but it does not have the monitars and such does the III have the float?

I will make sure to check that efore ordering to be on the safe side as I am in an apartment

Incidentilly, I'm in the process of building and then selling a complete 8-stage RO/DI system (dual 75gpd membranes and triple DI canisters) with 60-gallon storage barrel, 3.2 gallon pressure tank for drinking water, etc. for $500 cash

May be more system than what you need, but thought I'd offer it.

It is the ultimate system

I think that is a little too much for machine for me. :laugh:
