Red Sea Coral Pro salts

I'm thinking of getting this one:
http://m.marinedepot.com/products/sp12291/spectrapure-maxcap-ro-di-system-w-manual-flush

Would that be a good setup?

There's a lot of folks that use them. Though I don't use any brands 'units'. I do however use the spectrapure RO membrane. But that's what makes the filter right, not the plastic containers.... (build your own and you can stick any filter you like inside, helps you to learn the tools as well)

Are you sure it's 5 cups to 5 gallons of water?
(I could of sworn that I measured 0.6 lbs per cup of Red Sea Coral Pro salt.)

5 cups to 10 gallons sounds more like it.

In addition to the lower pH compared to many mixes, organic matter and phosphate get onto the growing calcium carbonate crystal surfaces, reducing precipitation, but it does happen on warm objects like pumps and heaters.

FWIW, the precipitation in the mixing container is not a big deal, IMO, and many people might like the lower alk you get as a result anyway.

Randy, would there be any way to increase the precipitation to get the alk on the lower end? I really like the RSCP but that 12 alk always throws my parameters.

Muriatic acid will reduce the alk no precipitation needed. It will in fact do the opposite and reduce the chance of precipitation on any mixing pumps or heaters in the mixing container if you use one.

Handle with care. It will burn. I pick mine up from a hardware store.

And FYI


Adding 1/11,000 of the water volume as muriatic acid will drop alkalinity by 1 meq/l (2.8 dKH).

Edit: thats not for the "green" reduced odor muriatic acid which is just diluted more.

I just switch to a different salt with lower alk.

 

[jason2459]

That works to. Or make it an excuse to buy more demanding stoney corals.

1. Go with Spectrapure or Buckeye Hydro, both are companies that specialize in water purification, I had a few poor RO/DI systems poor until I discovered Spectrapure
2. You only need to mix salt until the water is clear ( usually 2 hours)
