Interesting attack on Randy's two part

[tmz]

Fish food/waste and salt mix take care of trace and minor elements needed .Kalk or two part or a calcium reactor and some mag clhoride and mag sulfate from time to time .

Yeah, I knew about Mg and CaCl. You're suggesting I add fish waste? Seems there's plenty of that already.

Here's a DIY salt mix recipe, but you need reasonable access to chemicals:

An Artificial Seawater Recipe

For those who are interested, the following artificial seawater recipe is taken from "Chemical Oceanography" by Frank Millero. It makes a recipe that matches 35 ppt seawater in terms of major ions, but does not try to match all minor and trace elements, most of which will be present as impurities in the major elements.

23.98 g sodium chloride
5.029 g magnesium chloride
4.01 g sodium sulfate
1.14 g calcium chloride
0.699 g potassium chloride
0.172 g sodium bicarbonate
0.100 g potassium bromide
0.0254 g boric acid
0.0143 g strontium chloride
0.0029 g sodium fluoride
Water to 1 kg total weight.
