Phosphate Dosing

[ReefPig]

Howdy,

I've been Sodium Nitrate dosing for a while, but my Phosphates are super low, and I'm basically pouring food into my tank to even stay at 0.01 - 0.02.

I was looking at a local supplier I've used before (live in the UK) and there are a LOT of options, I'm somewhat confused with what the right one to pick is.

Options are:

Ammonium Hydrogen Phosphate 95% Calcium Tetrahydrogen Di-Orthophosphate Monohydrate Di Potassium Hydrogen Phosphate 98% ACS,FG Mono Sodium Phosphate Anhdyrous Food Grade Potassium dihydrogen Phosphate 99-102.00% Anhydrous ACS, FG Sodium di-Hydrogen Phosphate Anhydrous 99% ACS Sodium hexametaphosphate (Grahams Salt) Sodium Phosphate Dibasic ACS Tricalcium Phosphate N.F. Food Grade 35% di-Sodium Hydrogen Phosphate Anhydrous 98.5% ACS tri-sodium phosphate dodecahydrate

I'm guessing I either want Tri-sodium Phosphate dodecahydrate or Mono-Sodium Phosphate Anhdyrous?

Cheers,
Dave

I use sodium phosphate, dibasic
Na2HPO4

It is working well for me. I used the calculatorhttp://www.theplantedtank.co.uk/calculator.htm
