I agree it was kind of quick in adding so many in shuch a short time. I've been lucky not have have much die-offs from the 60lbs of tbs rocks (&25lbs of LS) and adding sm doses of Seachem Stability. I'm collecting much from the skimmer now as I've been very careful on not overfeeding and leaving food on the substrate. All the filters are on this tank and don't really have any where to to as the the quarantine tank is used for curing LRs for the future tank.
Between 2 filters, potein skimmer and one powerhead I've about 1,000 gph flow and I've been testing the water parameter 3-4X per week. I greatly appreciate your concern and suggestion and will keep a very close eye on them.
