Just wanted some clarification around the differene types of RO filters out there.
I have read on the forum that most of you are quite impressed the the waterboy units. Please excuse my ignorance around this topic.
I have seen a few types of units on the market, my question is what makes one better than the other if they are SABS approved, what do we look for when buying this type of unit, I have seen a puritech RO unit for R1300 then there is the Reefmaster similar unit for about R2500.
Its the different filters they use. In marine we want 0 TDS in our RO water. Most comercial RO units cant achieve this and they also have extra stages that add minirals to the water again that we dont want. The micron filters used by the Marine RO units are far beter at getting 0 tds
The store I went to claims that with the builtin resin unit it will bring down the TDS to 0, from the description of both products on the net they seem to be the same types of filters
hi, think it depends on the membrane in use aswell as the amount of prefilters and what kind of prefilters, you get mebranes that is rated for 50gpd, 75gpd 100gpd and so on, the higher the galon per day the more it costs.
When it comes to the waterboy unit it's not that its much better than most good RO units out there, it's just that marco has always kept the cost of these units down for us hobbyist. So you'll more than likely pay a few bucks more for the same quality somewhere else and from a few places you might end up paying a few bucks less than the waterboy's units.
BTW it's not just RO water we want, it's RO/DI (deionized) extra chamber with resin to make sure you get 0 TDS(total dissolved solids)

I paid R1700 for my waterboy unit. It is the reefmaster evolution with the resin chamber. It works like a bomb. You dont need the R2500 model. I actually didnt know that they had a marine model that expensive.
