how do i tell if this is a good unit or not, i've looked everywhere online and can't find any info on it, and also can i just just bulk carbon to change the membrane filters myself.

Hi, I have a brand new in box Coralife 50gpd RO/DI unit, I bought two when I did my upgrade but then changed the plan, has been sitting for six months never had water run thru it, If interested I will let it go for $100.00 plus shipping.

I have a ro/di unit I bought from melev's reef 2 years ago.Love the unit.
Just bought that WaterRidge Ro unit for my daughters aquarium. You will have to add a deionizing unit to it for the SW aquarium.
The WR unit has a tank and a faucett for your drinking water or fridge. I think it is a good unit, but have not tested it. The tank will give you about 3 gals at a time. It will be slow to fill. If I remember correctly, it will make 23 gals in 24 hours. Needs 50psi from the municipal water supply, which is really low. Lower mainland has a lot more than that.

The filters take the regular 10 inch. Lots for sale on ebay, reasonable. You will also find DI units there.

thanks hillegom, couple questions does this unit have to be installed to your sink or can i install it to a laundry sink, and also do i really need a di unit also for vancouver tap water?

No it does not need to be installed under your sink. But you do need a little bit of plumbing knowledge. There is a comprehensive guide included. You will have to plumb into the cold water pipe after the shutoff below your laundry sink. The drain you could just put into the laundry sink or the washer standpipe, securely fastened.
Yes, I would use a DI unit in Vancouver. I use one in Surrey, we get the water from the same source, don't we?
This is just one co. that has extras. you will need a housing

and a refillable DI cartridge to put into it and some plumbing fixtures to add the unit to the waterridge system.
The WR system also comes with a faucet for drinking water that you can attach, I guess to your laundry tub, or just do not use it. The tank, you could just put below the sink.
