Can you point me to the link on rasping? Do you just take the top surface of the rock off and then squirt Hydrogen Peroxide on the surface?rasping precedes peroxide use if you want it gone
on a test rock, not the whole tank, that way you’ll know how deep to rasp.
Peroxide is a fine fix, but it was used incompletely here. If you were to model rasping and peroxide in the right order on a single test rock, it would comply. The wait continues ~ the way we arrived at rasping was charting the use of peroxide for seven years in the way you applied it, then we invented rasping and 80% of the outcomes changed. not all, 8 out of ten, but a big increase sustained that’s for sure. With a single test rock your system would reveal if that way helps or not
