Ah yes...the best salt thread. We haven't have 1 in what...2-3 weeks?
Anyway, I will tell my tale...lol. I use Red Sea Coral Pro. I used Red Sea previously and switched to the Coral Pro when that came out. When I make up my new water, it tests about 480 ca
, 7 dKH
and 1325 mg
. The ca
is a little higher than I run my tank (about 430), the alk
is low and the mag is just right. So.....I dose baking soda in the fresh mix to get the alk
up to about 11 dKH
. Now what happens is since I also dose 2-part every day, over time my calcium starts rising. I had to make an adjustment to how much of each 2 part I was dosing. It's not equal parts now so I can't cook them both up at the same time.
The higher ca
in the salt mix just made things a little more complicated in my case.
I know alot of people and have seen some awesome tanks, the PSU 500g reef for example, where Instant Ocean is used. But that's not all. There was a thread on RC about this and I asked Sanjay about it. IO typically tests at about 340 ca
, 12 dKH
and 1100 mg
. So they bump up the ca
and mag in the new mix with the calcium chloride and magnesium chloride you can get from Bulk Reef Supply. So they make the mix to maybe 32ppt and then dose. Adding the ca
raises both those levels, plus it raises the sg
. You are now using less salt to get to 35ppt and you have your ca
levels all at optimal levels. It is actually cheaper to use IO and dose the ca
than it is to use IO alone to get to 35ppt! The cost for the amount of ca
to raise the sg
cost less the extra salt needed to get to 35ppt. IO is usually the cheapest to buy to begin with.
I think when I finish the bucket I'm using now, I'm going to try the IO.
