Everything I have read on Reef Central says they are a good company with a good product.

For what it's worth... I got mine off of EBay from a company called Aquasafe Canada. I have been very happy with it, and the support has been great. 6-stage for $95.

Jason,
do you have yours set up with an auto-top off for your water storage? My idea was to have it hooked up to my indoor garage sink and then have it pump into a garbage can that I will use as storage. I want to add a switch that would stop the flow of water so there is no chance of it overflowing.

You want to get a food grade trash can or food grade plastic RO water storage tank as opposed to any run of the mill trash can. The plasticizers used in el-cheapo trash cans contain a lot of phosphates. Storing water that has been de-ionized will suck the phosphates right out of those plasticizers and put them into your water and will end up in your tank. Rubbermaid makes a line of trash cans named Brute that use food grade plasticizers and that is what I use. (TDevil has some inside info). PS....even these have trace amounts of phosphates but they disappear rapidly.

Your other option is to fill up a regular trash can with RO/DI water and let it sit there for a week and then dump the whole trash can full of water down the drain. Fill the tank partially up again, let it sit for a couple of days, then do a phosphate test on the water. That will tell you if you need to fill it to the rim for a week again. You want to make sure that your test kit can be used on freshwater....not all of them can.

Good Post, Curt. Storage containers are often forgotten as a phosphate source. Why spend all the money on a good RO/DI unit, if you are introducing phosphates just from storage. My Brute cans have the wheel attachment, so I can just wheel them across the house.

I use the Kent Marine Maxxima Hi-S 60 gpd unit. I love it....my water is horrible. TDS reading of the high 400s sometimes into 500. The output is 0.

I'm currently using an Aquasafe Canada RO/DI unit that I got off e-bay/ 6 Stage 100GPD with storage tank. After I set it up I haven't had any problems with it and think it's the best investment that has been made towards my tank todate.

I also store my extra water in 5Gal water jugs. I find they are easy to move around, the lids are easy to get so you don't have to worry about contamination and I know they were designed for the purpose of storing water longterm without releasing phosphates.
