Lol I do the nopox only in emergency situations for short periods.+1
Fwiw, in 8 years ive never dosed anything like nopox . my gfo is 6 years old. I do however have a really nice scrub brush set.
I actually had a 150g with 200lbs of lr flowing with gha years ago. I bought out the homestore of 5g buckets and pharmacy of h202. I killed it all!!!!! Lol. I still have some of those rocks and to this day they don't get algae on them ironically [emoji12]
