Where is the best place to get RO/Di unit for my aquarium for reasonable price?

 

[jasonpatterson]

Buckeye Field Supply, Bulk Reef Supply, Swap n Shop, eBay. What you get depends on what you want to spend, of course, and the initial cost of RO/DI isn't cheap.

I am planning to spend around 150 - 200(Cheaper better). Where should i start? I might want to start salt water tank in the future so I wanna get something with Di unit.

Here is the BEST deal you can get for the range you want to spend IMO.

This one is below your range and has everything you would need to make perfect water (2 sediment pre filters, DI and RO).

This is at the top of your range and is a 5 stage system but had a dual reading TDS meter (to be able to see the drop in TDS from tap to product water and also a pressure meter and everything else you would need, ever!). If I ever have to replace my 4 stage (very similar to the top link which gives me 0ppm TDS product water from my ~300ppm TDS tap water).

just did a post about this earlier....

http://www.plantedtank.net/forums/equipment/151232-portable-countertop-reverse-osmosis-ro-di.html

bought one last night... Im a grad student so moving around alot is a problem. Of the research i did on the units, this seemed to get good reviews and seems pretty easy to setup

 

[gabloo]

Isn't 75GPD is too low? I m looking for around 100GPD + since i have big tank.

 

[UDGags]

I doubt you need 100gpd+...how large is your tank?

 

[gabloo]

I got 75, 55, 30 and 20 g tank. I m not going to use RO on all the tank tho.

I highly recommend this company: http://thefilterguys.biz/ I've bought two units from them over the past 7 yrs and think the units are fantastic, good price, etc. They've got a 5-stage RO/DI, 75 GPD for $135. You'd need to be sure you got a faucet adapter, etc., if you plan to leave it a portable unit. But they can add that in. For the price and quality, I'm not certain these guys can be beat.

 

[joshh]

Got a 100gpd at purewaterclub on the cheap and very happy I did.

 

[gabloo]

What do u think about this unit compare to 139.99? Is it worth play 60 dollar? what the difference?

$ 199.00 - OCEAN REEF + 1 FIVE STAGE 75 GPD RO/DI

also what difference between this two units? the other company is 30 dollar cheaper since is free shipping.

[discusonly]

First thing you need to consider is:

1. How much RO do I need to produce daily
2. What is my water source? Do I have adequate pressure?

Plan to spend on the average of about $150-$200 for a good RO/DI with the right accessories.

+1 on The Filter Guys! The more water you want per day will cost you more in cost. Mine does 300 GPD but is plumbed right to my tank for easy water changes.

The cost for a 75-100-150GPD isn't that much more. I got one from ebay which I didn't look clearly uses compression fittings instead of john guest fittings but it works just the same.

I have a 29G reef and opted for the 150GPD only because I'm impatient and use a garden hose adapter until I can find a permanent place for it.

The higher GPD filters are less efficient like 90%~ unless you get dual 75GPD or something but I can live with it for faster water production.

Do you mean the $129 system? I cant find a $139 system at BRS.

If its the $129 system here are the features that the $199 system has over it.

-5 stage unit v 4 stage unit that includes the filter I describe below.

-It has a finer pre-fiter that is specifically for removing very fine sediments and chlorine before water hits the RO membrane or DI chamber.

-comes with an auto shut off valve

-has the dual TDS meter built in. This is a great feature and I constantly go back and forth about purchasing one to put on my system (~$30 to purchase from here, BRS) as it gives you instant readings on the water where you choose to set the probes at. You could set one before the filter to get a tap water TDS reading then put one on the product water line to see what the TDS is after complete filtration. You could also put one pre RO membrane and one after to see how effective your RO membrane is performing (since it actually removes ~90% of all water contaminants). The possibilities are endless but it would be a very valuable tool that would allow you to constantly measure your systems effectiveness and also let you know when you should replace filters.

- has a flush kit for the RO membrane. I have never used one but this could extend the useful life of your ro membrane (most expensive single filter) 3-4 times then without one.

- has a pressure gauge which you put inline. This is also a good tool to help decide when filters need to be changed as a pressure drop from whatever the pressure reads when first hooked up would denote clogged filters (normally just the pre filters, not the RO membrane or DI resin chamber).

Do you have any idea what the TDS ppm your tap water contains? If its below 400ppm the 4 stage system would be fine (it would be fine with higher ppm tap water but you may have to replace pre filters every 4 months instead of every 6-8 months, which is what I do).

You can increase the GPD of any unit but you just need to make sure that the membrane you have is rated for close to whatever the flow restriction module you put on it is.

I just asked this question not long ago but haven't jumped in yet, but BRS has videos and will answer the phone, I tried emailing the pure water club and it's been aleast a week with not reply other than the auto reply. When your buying these units it's good to know a little about your water so I would test all you can or get a water report for your area, this will allow them to tailor fit your unit, slower units clean better and need less in the gizmo dept., the filter guys seem really good as well.

BRS does have some of the best customer service I have ever had the pleasure of coming across. I emailed their online rep for a couple of weeks (who is awesomely named Brandon so he had an auto +1 in my book!) asking a TON of questions about just what kind of filters I needed to purchase when it was time for me to replace the pre filters. He answered my questions thoroughly and thoughtfully.

If you want to compare apples to apples you should be comparing the filter guyz system you linked to this kit from BRS.

Is there any specific reason that you did not consider the above linked BRS system or are interested in the cheaper 4 stage unit?

All in all they look to be about the exact same except for the filters that are used. And of the filters the only one that looks to be different is the first stage purely sediment filter. The ones from BRS are the industry standard and you cannot get a better filter unless you want to drop some serious coin, which would be completely pointless.

The BRS has a chrome faucet connector and since the FG's system doesn't say theirs is chrome I would assume that it is plastic. The BRS system also has a Utility sink/garden hose adapter and it does not appear that the FG's model has that.

So the BRS has a few not too huge extra accessories and Customer service that is unrivaled in the business. I actually did email the filter guyz as I emailed about 4 different companies about the filters I needed to replace and of the 4 FG's was the only company that did not respond, I actually sent a second email as it is possible that I screwed up and didn't send the first one somehow but after a week of no response on the second email they were crossed off the list for sure.
