First ro/di unit

Ok so im getting this ro/di unit i know its not the best but im just wondering what i should do as maintenance change any filter take apart and clean or what and can you change the carbon in the one part of the unit here is a link for the unit (if it works) http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemVersion&item=260494398421&view=all&tid=0

0 PPM Portable Reverse Osmosis RO DI Water Filter 100 - eBay (item 260494398421 end time Oct-27-09 19:22:03 PDT) try this one

 

I would think twice about ebay quality RO/DI systems, you really do get what you pay for with RO/DI. What may visibly look similar usually is not even close in quality.
It almost always ends up costing you much more to replace and upgrade a lower end system than if you had spent the $150 on a good true reef quality system to begin with. That $150 gets you name brand filters in the correct micron ranges, solid carbon blocks instead of inferior granular carbons, a Dow Filmtec or other name brand RO membrane, full size 20 oz vertical refillable DI canister and cartridge, an inline pressure gauge, a TDS meter, metal brackets, John Guest speed fittings and much more. Normall you add the cost of a TDS meter and pressure gauge to an ebay system and you are close in price already and still don't have the quality of a better system.
The link takes you to your log in page not the auction.

 

How can u test ppm to make sure it is working?

 

Not really a good deal at all.
It uses non standard size replacement filters which cost more, are harder to find, do not come in many micron ranges preferred for reef use and do not last as long since they are smaller.
No bracket, no pressure gauge, no TDS meter, no full size DI etc.
You have about $60 in it already and still need a TDS meter at a minimum to even see if it works or not.
Thats another $20 or $30. Then you need a pressure gauge to monitor the condition of the prefilter and carbon, another $15-$20.
The waste line is missing so you probably need a flow restrictor, $5-$10.
The system has been sitting idle so the DI resin has dried out and is shot, $8-$20 for replacement.



Take a look at the $149 Pro Plus here:
SpectraPure Customer Appreciation SALE! 20% - 50% off

First off they are a 3Reef sponsor and stand behind their products with a 25 year company history located in the same town in AZ all that time.
You get a complete new system with everything I mentioned plus a performance tested RO membrane, hand blended DI resin, a warranty and much more.

I'm not in any way trying to dog you but buying used RO or RO/DI equipment is very risky and usually isn't a good investment.

 

Im not worried about pressure guage or waste line that all i have i understand what your saying about quality but i do not have money like some other and my lfs never have water and i know all they have is a cheap setup too so who knows what i have been putting in my tank thus far ill give it a shot its not like i havent wasted 60 bucks before lol but is there some kinda test strip or drop test to test for ppm and where would i get it

 

neer mind thats why u said i need tds meter just learned that is what tests the water lol thanks for your info i will see what happens with it and get back to ya if it works for a couple months ill be happy

 

I have the same Ro/Di unit I purchased from purewaterclub a few months ago and test the water weekly with a TDS meter and get 0.00 PPM every time. I'm sure there are better units out there but for the $$$ it can't be beat IMO

 

Got my 70 GPD from TB Aquatics via eBay, and i love it...... Great costumer support too.
