What is a good source for sodium sulphate used in the artificial seawater recipe?[?B]
The lack of simple availability for most people is why I haven't made DIY recipes with it.

If sodium sulfate is not used, what is the recommended alternative? Magnesium Sulfate? (and then adjust the amount of magnesium chloride?)
For a salt mix, you can do that, yes.

I think that depends on the individual Univar Outlet, as I've seen posts about buying Calcium Chloride 77-80 where the hobbyist was told "pallet loads only"
However, I routinely buy individual bags of 20K and 25K (depending on which chemical) from the London Ontario outlet and have been for quite a few years now.
The sodium sulphate I buy costs $14.00 CDN plus taxes of 15%.
If you're in the US where I.O. and other salts are relatively cheap, you won't have a big savings I wouldn't think, but for here in Canada where I am, a pail of I.O. costs $59.99 plus tax for a total of $68.99 and only produces about 140g US mixed to 1.025, for a unit cost of just over 49 cents a US gallon.
My home made mix I just made, works out to just under 9 cents a US gallon mixed to 1.025.
Please remember though, I'm not using this mix in a reef as it is not a complete salt mix, but I use it 50/50 with I.O. in my fish only tanks.
It's great for my brine shrimp and mysid growing operations. (the brine shrimp operation is large, not just for an individual hobbyist)

Again you were right.<a href=showthread.php?s=&postid=6610119#post6610119 target=_blank>Originally posted</a> by Randy Holmes-Farley
In this situation, yes that sounds good, but more aeration may take the pH back down again.
The water basically goes back to the same readings within about 18 hours.
As I need aeration for the brine shrimp grow operation, and, with my fish only tanks I use the mix in, I have very large airstone skimmers, I guess I need to find another solution.
Is it possible that one or more of the chemicals I haven't used from that formula you posted, would keep the pH and alkalinity in line?
Thanks again.
Higher alkalinity contributes to more pH stability. Most of the others play a pretty minor role in pH.
