RODI

[BillBME]

Well... it seems like it's time (overdue actually) to purchase an RODI system of my own. I'm looking for suggestions on what might be considered the decent one of the day. They all seem virtually the same. Is everyone ordering the same thing from china and then putting their own sticker or logo on them? is it hars to become a dealer, just curious about that part, but I do need to narrow it down to a decent purchase. 75 gal. per day probably. we have do chloromines. city water. SPS, anenomies, fish and live rock.....
Thanx much,
b.

Don't buy full units, it's like you said. China, stickers, etc.. At least I'm sure 99% of them put them together the same as what you can, except then you'll be paying for extra costs.

Goto marine depot, get the .5 micron sediment, then 2 of the .5 micron carbon blocks, a RO membrane, anion silica resin from filter guys, and then 2 canisters for DI resin, and an inline tds meter.

Thank you folks for the information, the spectrapure looks like a decent unit with everything i need for a decent price... others?

That spectra doesn't come with an auto flush

 

[BillBME]

Is the auto flush important, or is there a work-around possible.. i am not really up on exactly what is really needed and what is good to have for specific reasons..

Flush kits are a waste of money as are chloramine carbons. ANY 0.5 micron carbon block is more than capable of removing the chlorine portion of chloramines and breaking the bond with the ammonia which is removed by the RO and the DI, NOT by the carbon.
Buy the $125 Spectrapure refurbished system or better yet the $160 system which includes replacement filters and spare DI along with a handheld TDS meter and low range chlorine test kit. You won't find a better, more capable system anywhere, guaranteed.

There is one item that is not included with any of these systems that I think is beneficial. When you order, add a three way ball valve which will be installed between the RO membrane and the DI unit. When you first start to make your RO/DI water, the valve will allow you to redirect the effluent from the RO membrane away from the DI resin for a few minutes to flush away any TDS creep that may have occurred from the last time you used it, extending the life of the DI resin. This is not a flush kit.

Honestly i got a 6 stage off ebay for under $120 and added my own dual DI. Over some time i added pressure gauge, flush valve and dual TDS meter. You dont need to spend alot just be smart about what you are looking for. best of luck

Thanks for all the reply's, nice to have all the knowledge of the forum right at hand. it helps sort things out, and give a person something to think about or to know what to look for. getting back into reefing after a few year off, many changes and ive got to get back into a decent schedule and conduct this orchestra of new equipment in a fluid/functional way. Ive already let things kinda go in my small tank (10 Gal.) and ive got Brown Bubble diatom algae making its way all over some nice new corals. I'm moving to a 20 gallon Long, and hope to clear things up. Ive cut back on the light hours and will be changing all the water out with new RODI saltwater. I was already dosing Kalkwasser and managed to let that get out of control, hence a bad PH spike, and a new lesson learned. Taking a deep breath and now trying to move forward sans mistakes. Thanks again for everyones help. Look forward to future discussions.
