RODI with booster: which one

[alisa1965]

I have a 90 gallon tank. I try to do a 10 gallon water change once weekly. If I invest in a RODI system, I need a booster as well. Where can I find a reasonable system, what should I look for, and how can I simply hook it up? I know there are apartment ones that can hook directly to the faucet which might be an option but are they good? I found some systems on ebay with 5-7 filters. Not sure how many I need, tho. What do u think? I also want to be able to get filters locally if needed.

All you should need is a 4 stage filter, a carbon, sediment, membrane and di. Look for a system that has verticle di stages, a pressure gague and a tds meter, might have to buy the tds meter seperate but you need that and pressure guage to tell if your filters need changing or not. Look for a system that has a 75gpd membrane, they have the best rejection rate.

Buckeye hydro
Spectrapure
The filter guys
Bulk reef supply
Air water and ice

Those are all great places to buy a quality filter. Most on ebay are more for drinking water rather than fish tanks and to make them better costs alot more for the upgrade.

As for the booster pump look for the aquatic 8800 pump kits.

Make sure that your municipality doesn't use chloramines though. If they do you'll need a system to deal with that.

I have well water which is why I also need a booster. What do you thin about this unit? I would still have to purchase a separate Booster for it, tho. http://www.ebay.com/itm/0PPM-Portable-50-GPD-Reverse-Osmosis-RO-DI-Filtration-/110691608751?hash=item19c5bbe8af

Not a good choice imo, those replacement filters will have to be bought from them they are not interchageable, does not come with a pressure gague or tds meter. And one of the worst rejection rate membranes.

Look to spend around 250 for a quality unit with booster pump.

That is a great unit, add in a tds meter and a booster pump and your set.

Is another good unit, make sure to get the 75gpd membrane

FWIW having a well does not automatically mean you need a booster pump. I was getting about 50 psi out of my well pump, invested in a booster pump to get up to 80, and it's made a negligible difference frankly.

[alisa1965]

I have maybe 20 pressure with my water. Tested about 6 months ago. I found this online thru craigslist. Unsure about it tho. http://jxn.craigslist.org/for/5131070242.html

You will need to buy all new filters for that unit so add in an extra 100+ to get it working, still need a tds meter. Imo you can buy a brand new unit for that price.

Stay away from that unit

The best bang for busk unit is the Spectrapure refurbished 4 stage. The more pressure you can get to the membrane the better. When you plumb a booster pump place it between the carbon block and the membrane. This way the sediment and carbon filters can filter out any particles that could damage the booster pump

I live in NYC where we have great source water. Chlorine and flouride is added by our city. I tested water from the tap and it contained low levels of both.

I use the RO Buddie (http://www.amazon.com/Aquatic-Life-Reverse-Osmosis-100-Gallon/dp/B00DOG64FM) and added a flush kit and pressure gauge myself. Because I live on the 3rd floor of a building I had to get a booster pump (http://www.amazon.com/AquaFX-RO-Booster-Pump-Complete/dp/B00MYHO4QS/ref=sr_1_1?ie=UTF8&qid=1442190608&sr=8-1&keywords=aquafx+booster+pump)for best performance.

I would've gone with the BRS system but I simply don't have room for it. I can pull out my compact system when I need it and pack it away just as fast. I also made sure to have a 9 gallon ATO contain which top off once a week.

[alisa1965]

Problem is the RO Buddie is just that: "RO" not DI which is also what I need.

What do you think of this one?

Sorry if I didn't claify enough.

It's a full RODI system when the DI attachment (http://www.amazon.com/Aquatic-Life-Color-Changing-Cartridge/dp/B00DSP57BQ/ref=pd_bxgy_199_img_y) is added - which I did add.

The DI resin is refillable so I don't have to purchase it new everytime. I purchase DI resin in bulk from BRS.

I have well water, use a Spectrpure with booster pump. I highly recommend it. Talk to Jeremy over there, he'll help you out.

As has been mentioned a few times in this thread. Get a Spectrapure unit with a booster pump. Also, I would highly recommend checking your water for Co2. Co2 will kill your cartridges in a hurry. If you have Co2 in your water which is very common with well water, you will want to use a cistern with an airstone or something to aid in the outgassing of the Co2.

For folks on a well:

I often see people on well water make statements like "I'm on a well and have 45 psi."

Realize that well pumps are what create that pressure. Well pumps are controlled by a pressure switch. There are two common settings on these residential pressure switches: 40/60, or 30/50.
40/60 means the pump kicks on at 40 psi and off at 60 psi
30/50 means the pump kicks on at 30 psi and off at 50 psi

So when you're on a residential well, your water pressure varies! It is not a static x psi.
