A question about switching salt

[Keri]

I'm in the process of setting up a 120 (still painfully waiting for the RODI to produce enought water) and I'd like to change salt brands. I still have more than half a bucket of red sea pro coral salt but I want to switch to instant ocean. I'm not so impressed with the RSPC that I feel it's worth the price difference between the IO and I see a lot of people with BEAUTIFUL tanks on here using the IO.
My question is: can I use the rest of the RSPC salt PLUS IO to get the 120 started and then continue to do water changes just using the IO?

Thanks for your input!

do you have enough RSPC to fill the 120?? are you upgrading / moving a tank?? or are you starting fresh??

i find that if you start off with small frequent water changes to not shock the tank you can easily switch salts with no ill effects.

you should be fine if you just do 50/50 mix of each until you run out of RSPC..

Yes to your first question.

Just finish it off and then start up with the IO. You don't always have to 50/50 it if there is nothing in the tank to impact.

Whoops... my bad.. I read it as switching to a bigger tank, not starting fresh... damn, monday mornings.

I would just use both salts and after the water is well mixed thoroughly test the new water.

I have used IO for years and I find it to be low in both CA and MAG.
