Hi all, I was wondering if anyone here has used purigen and discus buffer by Seachem and if it works as it claims - to lower TDS and to soften the water. We're lucky here in Malaysia in that my water off the tap reads at 100 (i don't know what unit my meter uses) but i saw some postings by discus folk that heckels and santa isabel angels need a tds of 50 or lower before they get triggered to spawn.
