And only IO users, please. :D
I'm doing a little survey of what calcium numbers IO users are seeing in Instant Ocean these days. I thought it ran around 340-350 for the longest time. I recently purchased a small box and tested @ 35ppt and got 380 (with 3 different kits).
So please, fellow RC'rs help me out here. Just answer four questions for me.
1. S.G. mixed @
2. What method of testing s.g
3. What brand calcium test kit
4. Results - Calcium ppm
Thanks all.
:)
