Guide: Lanthanum Chloride dosing for Phosphate control

[Thales]

Thanks-by what you posted -I am dosing about 22x more than that!
So how much are you dosing now?
And what was PO4 starting point & current?

Maybe I will reboot lanth but I want to see it basically gone from the system before I do so.

50ml/1 gallon of DI dosing between 200 and 400 ml/day (depending on phosphate level)

Phosphate starting was like .9, currently between .15 and .4

Assume you mean .4????

I'm sure it's gone already, assuming your system is producing some po4 for it to have bound to (and if it isn't...you don't need to worry about managing it in the first place).

I am using even less LaCl than @Thales - a 10:1 RODI:LC dilution, but only about 4ml of this per day, spread across 4 doses of 1ml each several hours apart. This keeps my po4 in the 0.05-0.1 range.

What makes chaetogro a brute force method in your opinion

It is a 'fertilizer', which they even openly state in their product description. I do not believe a 'fertilizer aproach' is advisable for trace element dosing except in some very limited circumstances, i.e., you have so much crop that you know it will all be absorbed by all livestock immediately.
