Dennerle Plant Care P - Fosfaat

I've been fighting pale, stunted growth in my stems for months, and adding this phosphate turned things around within a couple of weeks. The dosing is precise enough that I can keep that trace level up without worrying about algae taking over.

My tank's floating plants had been stalling for weeks, but two doses of this phosphate got them growing again without a single algae spike. The liquid is easy to measure with the included dropper cap, which makes dialing in that trace level pretty foolproof.

My Amazon swords were showing phosphorus deficiency despite root tabs, and this cleared it up within a week. The bottle is small but concentrated, and one capful treats my 40-gallon tank for weeks. Only wish it had a dosage pump built into the cap.
