Quick rock curing

[donkey77]

iam cooking some LR right know in saltwater with a good power head and a heater with a temp about 85, i change out the water every week the rock had high posphates, is this the best way to get the phosphates out, i plan to run like this for a 6-8 weeks or should it be in freshwater

Do it in salt water. Phosphate behaves differently in salt vs. freshwater. All the different chemicals in salt water push phosphate to form a different ratio of species, and since you're going to be using the rock in salt water you want it to reach equilibrium in salt water.

This. Phosphate speciation is affected by pH, and you're better doing this in water close to the tank parameters.
