Dosing seachem calcium?

i'm currently using seachem reef advantace calcium, in the powder form. I was wondering if I could mix the 500 gram bottle into a jug of ro/di water and dose it like a two part? versus mixing in water a little at a time. will it loose it's strength being mixed up and sitting in a jug?

also, is it safe to use at the same time with my alk supplement. i'm currently using the alkalinity part of randy's two part.( I live deep in the south. so I have never been able to find a suitable de-icer to make the calcium part) the instructions on the bottle say not to use it the same day as any alk suppements. what adverse affect would this have? sorry if i'm rambling.

That product can be premixed without issue. It should be fine to dose along with alkalinity as long as the parameters are in reasonable shape, and the area in which you're dosing gets good flow.

Why now just dump the required amount directly in powder form?
I use baking soda and Reef Advantage Calcium directly in the tank

Undissolved particles might land on animals and irritate them, or just fail to dissolve if pumped somewhere, but that's the only issue I've seen brought up.

Well I dump in the sump/overflow, no worst than adding 3-5% of RO water as top off directly in the sump/refugium.

Hi
I use Seachem reef advantage calcium and reef builder and was told by Seachem NOT to dose both together as one is a negitive ion and the other is positivley charged and this will cause one of them to precipitate, I was told to dose on alternate days or at the very least one hour apart.

I use seachem reef advantage calcium in my topoff tank of twenty gallons which drips into my sump. I also dose with the seachem reef carbonate to raise alk. This is doneby mixing into ro water and pouring into my overflow. It is working well for me but expensive and time consuming on my larger system. I will be switching to kalk water in my topoff tank and hopefully, a calcium reactor down the road.

I am not a fan of Seachem Reef Calcium because of the polygluconate.

The Reef Advantage Calcium can be used in this application, but bear in mind that it may or may not already be ionically balanced, and does supply some magnesium and strontium.

Randy...Can you elaborate on the polygluconate? Do you have an article on this you could post.

I discuss my concerns with it, and have a link to my discussion with Seachem about it here:

thanks for the replies. randy, I read the post about the seachem containing polygluconate. whew! that stuff is WAY over my head

randy, do you know how concentrated the mixture would with 500 grams in one gallon of water? would it be similar to the diy supplement?

You can use this calculator to estimate the potency of the mix you are using:

Reef chemicals calculator
http://home.comcast.net/~jdieck1/chem_calc3.html

Using it I get about 53,000 ppm for a 500 g/1 gallon mix.

Randy, I think you are mistaken as Reef Advantage Calcium use Blend of calcium, magnesium, and strontium chlorides. Only the regular Reef Calcium use gluconate.

Reef advantage calcium if very nice as it maintain MG/SR and I only need to dose baking soda.

I think that is what I said, but perhaps I did not make it clear enough. The first sentence is about the polygluconate product, the second is about the Reef Advantage Calcium..

"I am not a fan of Seachem Reef Calcium because of the polygluconate.

my bad, but I guess it's balanced as it's only chloride ion like CaCl

Yes, my point was that I do not know if it has any sulfate in it or not.
