RO system: Is this one any good?

I will have a chance to buy this at a pretty decent discount soon, but I want to know if it will be OK for aquarium use. I've read all the specs and the reviews sound good, but those people are all just using it for drinking water. It has a "remineralizer", but does that add the right minerals for fish? I just want someone famillier with RO to take a look and give me an opinion. Thanks in advance.

Sorry, can't answer your above questions, but for $60 off Amazon, the ROBuddy unit is a great option:

I think you would probably want to bypass the remineralizing function of the above system for aquarium use and manually add back in the right minerals at the right dose for your tank.

If planning on using this for water changes try to figure out the gallons per day it creates. The post for it doesnít say which is odd for an ro unit and I think the container is about 3 gallons so this could be a very slow ro unit designed for 1 to 4 people which usually means about 3 gallons a day or so. I am obviously sure it has the capacity to make more than that but if you have 100 gallon tank do you want something that will take the entire day to fill up a 50 gallon container for the water change. I have been researching one for a fish room so thatís why this is on my mind

Last I heard (a long time ago) AO Smith was a highly reputable company. Maybe they still are.

This is a good RO(DI) system:

What you may want to do is to compare the SpectraPure features and benefits to the AO Smith. If they align acceptably, you are probably safe with the AO Smith.
