Water Filtration Method

That would work great... If you don't want anything fancy in your tank.

Good point; I forgot to include my potential stocking list. That will have a bearing on it for sure.

My preference is for a lot of movement in the tank; therefore I'm not going to be having any SPS (for some reason they just don't speak to me). The corals will be Elephant Ear, rose bubble tip, xenia, frogspawn, hammer, torch and green star polyps (GSP); etc. And to note, the GSP will only be allowed to grow on the side walls of the glass (to be kept in check with razor blades). I don't want that stuff anywhere on the rocks as I know it will slowly take over.

I find this to be a load of bull , no offense but my system is all tap water for years I have no problems keeping " fancy " things or what ever that's supposed to mean lol and im not cheap and comsider my taste very highend so I don't buy common stuff .....so maybe you can enlighten me as to why I wouldn't be able to keep fancy things using tap water exactly? Maybe I'll learn something new lol

Your method of filtration is fine but I wouldn't use DI resin as it will get depleted faster than having run in conjuction with a membrane.
I thought of doing a similar setup to my system running only filtration with no membrane as I like to keep some of the ions after filtering to go to my system...

That's something I hadn't thought of; thanks for that point of view. That would mean I could go with 3 sediment and 3 carbon (assuming I use 2 of the 3 stage systems; of which I already have one). You just saved me some money; which I'll use to buy some dry rock from you once I'm ready for it……wait a minute, I see what you did there! Very clever!

I'd just do a sediment filter and two carbon filters, should be good enough for your needs depending on source water quality. The extra sediment filters will do nothing unless you stagger micron sizes from high to low (night let you go longer between changes), but that would still end up costing you more. Sediment filters are cheap tho, but still I'd just run a single 1 micron filter on the front end and change it when your output drops significantly.

As for carbon filters, two I probably overkill but if you have the stages for it anyway it's just insurance. You can run 0.5 micron carbon blocks if you want but you would probably have to change them before the carbon is exhausted.

All of my RO/DI system's waste water travels 50' to a 55gal plastic drum in the laundry room. I coordinate washing clothes around when it runs so very little is ever actually wasted. There is an emergency overflow drain on the drum so that it doesn't overflow onto the floor if it gets too full.

An RO membrane is cheap why not just run a regular unit and skip the resin? I would imagine it's the membrane itself doing most of the work and a high rejection rate one is still reasonably priced and last a few years if you take care of it.

out of curiosity how does this work? normally you're feeding water under pressure to the machine and I'm guessing a solenoid in the machine opens and closes. is the barrel elevated to gravity feed into it instead?
