Cycling Dry Rock Question

JT_W · Aug 20, 2016

I've been cycling my dry rock in a container using RO water for the last week to remove phosphate before putting in the main tank. I've tested 4 times and the readings are 0.00

I'm using 70 pounds of Marco rock. Is it possible this rock has no phosphate or does it take time to leech out?

I'm using Hanna checker

If it had even moderate levels of phosphates they would be detectable by now. Assuming your test kit is good the the rock should be fine
