Red Sea Foundation A

Allen · March 14, 2021

Since I changed back to Red Sea Coral Pro salt, I decided to slowly switch additives to Red Sea as well. Starting with Foundation A which is calcium, compared with seacham I used to use for a very long time. Red Sea is slightly better value for money and it is easier for me to use as no need to weight and mix the powder anymore. It doesn't leave residue in the dosing container which is another plus. I guess it is the same with all liquid type additives. The bottle can even be connected to the dosing pump directly, so no more dosing container. Also, Red Sea says their Calcium includes Strontium and Barium which are used up at same ratios as calcium, so its great to be keeping all three chemicals balanced at the same time.

I still dilute with RODI water to use with my dosing pump for a more steady Calcium level. My calcium is kept at 450. Also checked the red sea my recipe, the recommended dosing amount of each element is slightly different then my calculated amount but it is a good starting point for some one just started and can slowly adjust to their own situation.

The Red Sea Recipe Widget, for supplementing is pretty cool. You can check it at: https://www.redseafish.com/myrecipe/

My recipe for a mixed reef with balanced color and growth is Salinity 34 ppt, Calcium 450 ppm, Magnesium 1350 ppm, Alkalinity 11.5 dkh, Nitrate 2 ppm and Phosphate 0.1 ppm. I found PO4 0.1 ppm is a little high for my tank and I like to keep it under 0.1ppm. So overall, very happy with Red Sea Calcium. Next, I will try their trace colors. So far, I found the red sea progrom is easy and simple to use. Again, just my two cents. Happy days!
