snowpunk Posted September 18, 2008 Share Posted September 18, 2008 I have one of these units that came with my setup about a year and a half ago. It is the 3 piece one from equinox. I had always bought water from seahorse(rock2) so I just put it in the closet. Now I pulled everything extra out and I am curious as to how it actually functions both inside and outside. I read over it a little and figured that it is a 720gpd unit, that is rated for 1000 gallons before it needs "a tune up/recharge" I don't know as I have never used one. I do tend to understand these types of things well, but I have never even looked into it at all. Is the one I have even worth using or what???

markdadof2 Posted September 18, 2008 Share Posted September 18, 2008 720 GPD? that is insane. My RO/DI unit is a 100gpd and it is more than sufficent. If it is truly 720GPD I would question the thought that it is truly RO unit. Does it state it is a RO unit? Quote Link to comment Share on other sites More sharing options...
snowpunk Posted September 18, 2008 Author Share Posted September 18, 2008 ahhh, I better go double check...(whistle)(whistle)(whistle) Quote Link to comment Share on other sites More sharing options...
snowpunk Posted September 18, 2008 Author Share Posted September 18, 2008 It says max rate of .5 gpm... so that would be 30gph, and 720 gpd, yea??? That does seem a little bit much compared to other ones I have been hearing about. Now I have more questions because that is the label on the first tube, and all that seems to be is a water filter, which makes sense as to why it makes that much. I guess what I am really asking is what is going on in the tubes, and what should I check before I start trying to use this water in my tank. I know there are a few gurus out here that know all about this... Quote Link to comment Share on other sites More sharing options...
Guest LisaJill Posted September 18, 2008 Share Posted September 18, 2008 If you decide to try to use this, at the very least use a TDS meter, and test nitrates and phosphates. My other concern would be depending on what stages it covers - if it'll remove chlorine and chloramine if you have them; not sure if there are test kits readily available for those. Of course, Prime or similar can help you there if needed. Quote Link to comment Share on other sites More sharing options...
vanz Posted September 18, 2008 Share Posted September 18, 2008 Can you post a picture? That's probably just an RO unit and the three chambers are just carbon. Quote Link to comment Share on other sites More sharing options...
ghiggi Posted September 19, 2008 Share Posted September 19, 2008 It sounds to me like it is just a 3-stage water filter and neither a RO nor DI unit. Considering it is an older equinox unit, I would guess the first stage is their standard 5 micron prefilter, the second stage is probably their special blend of activated carbon for organic compounds and the third stage is probably their blend of activated carbon and ceramic media for non-organics (lead, chlorine, etc.) While using it would be better than using non-filtered tap water, it's not going to remove nearly as much as an actual RO/DI unit. But, depending on your tap water, it may be enough. I'd test the tap water and the filter output with a TDS meter and test for nitrates and phosphates to see what the difference is. If the output comes up clean, then I'd say use it. Or, you could always purchase just the RO and DI chambers to add to it for less than a whole new system.

snowpunk Posted September 19, 2008 Author Share Posted September 19, 2008 I think your right. For now I am gonna just stick to the water I get. Still trying to get rid of the hair algae growth from long ago so I don't need to give it a chance with non RODI water. I may look into the 2 add-ons later, but I'm good for now. Thanks guys Quote Link to comment Share on other sites More sharing options...
