Tropica Premium, Masterline Golden or APT Zero?

Hi all,

and my micros solution using Rexolin APN and calcium chloride?

No, you will have the same issues, some insoluble compounds forming. I honestly think you are over-thinking it.

The smaller tanks however are getting smaller weekly water changes so I will need to supplement calcium in the fertilizers.

I'd just dose a small amount of dry CaCl2.nH20 every week. If you don't mind adding some carbonate hardness as well (dKH)? A small amount of <"Cuttle bone or shell grit"> will serve that purpose.

cheers Darrel

Ok got it, thank you!

Did I get it right on separating the macros and micros solution?

Do I mix the urea, Potassium dihydrogen phosphate, Potassium sulphate, Potassium chloride and Magnesium sulphate into 1 solution, and the Rexolin APN solo in another solution?

Does either of the above solutions require Vitamin C powder and Potassium sorbate?

Yes, both would require potassium sorbate and ascorbic acid, according to the IFC calculator.

I just realized something - most "trace" mixes include potassium together with the trace elements. Should I mix potassium chloride and sulphate in with the Rexolin APN as a trace mix; and mix the urea, monopotassium phosphate and magnesium sulphate together as a macro mix?
