sliming from water changes

[michaelg]

I am nearing the end of my bucket of IO. I had used oceanic salt for a while, and noticed that corals do not "react" to it from a water change. IO always causes my corals to slime up bigtime. Considering Tropic Marine or another salt. Anyone using the Tropic Marine Pro-reef salt? It is a bit more expensive and wonder about the value- namely reefcrystals isn't really worth the extra money over IO....
I remember Toyota guy mentioning some issues with changing salts and ESPI saying something about leaving skimmer off?????

Anyone care to elaborate?

what is PRO-reef ?

I just use the normal Tropic Marin.

Oh, and Linda and I are going to be ordering a big amount of Bio-sea from www.aquacraft.net if anyone would want some later this month.

Are you letting that water 'condition,' ie, roiling it with a pump for a number of hours or even overnight, before adding it to your tank?

FYI, I use Oceanic, and a fairly short mix period, about 6 hours, and have never had any sliming or ill effects.

Water is mixed days in advance with a powerhead continually and a heater to equilibrate. RO/DI water. Salinity checked with a refractometer.

The Pro-reef mix is something new- I saw it in foster's and Smith website- mentions something about the buffering being more compatible for reef tanks- whatever that means. See Eric's article from this months Reefkeeping for a healthy dose of skepticism.
Not particularily about this salt, but more a general thing of stuff in this hobby.

When I used TM, I rarely let the water sit for longer than an hour before use with a powerhead or just my hand mixing it.

Never had any issues.

just a fyi.
