I saw an article from Jack Wattley in the Jan 08 issue of Tropical Fish Hobbyist. He was recommending 40-50% wc
's daily for Discus.
I'm thinking about getting into Discus, but I couldn't imagine the feasibility of doing manual wcs like I do at that frequency and of that size.
So I thought, maybe I could automate it with a skimmer and auto topoff device, and pump. At $100+ for each of the 3 elements, that didn't seem realistic either.
So then I thought, why couldn't I install a toilet auto top off device like you get at Home Depot or Lowes? That would save on cost quite a lot. Then it's just the question of how to slowly release water into a sump and the toilet topoff would take care of the rest. To release the water, maybe it's as simple as a siphon hose with a ball valve set to just slowly drip. Anyone tried this? Any advice on how to succeed with it?
