RO/DI Filter - Purchase & Installation

[forestaquarist]

Hello All
I need some tips and helps.
I am new about RO/DI filter and is going to buy one. I found this one:
http://www.**************.com/brs-5-stage-plus-ro-di-system-75gpd.html
My tank has different inverts and 6 fishes, and of 75 gallons plus around 20 gallons of sump.
- Is this model good enough for me?
- I expect there will be some installation instruction, but it would help if you can briefly tell me how to install it.
- I heard there are some kind of wasted water...What is it about?
I still can choose some other model if u tell me there are better one (or better price)...
Any input is appreciated...^_^...
Thanks.

There or an Air water ice model.. the 75g per day is one of the best as far as longevity goes...for almost any brand..

I have a Typhoon III from Air Water Ice as well. It is awesome! And well worth it.
The waste water is the water that is "dirty" and can not be "cleaned" by the semi-permeable RO Membrane. The "dirty" water goes down the drain and the clean water is then run through additional filtration or into a collection chamber. The collection chamber is either a pressurized container that fits under your sink OR it could be a food grade plastic container that has a float valve. Also, you could install your RO unit next to your laundry and use the cold water tap as your supply source and the washer drain as the waste water drain.
I hope everything works out - and good luck in your endeavors.
