I've never target fed my corals at all, well, actually I did buy a bottle of Kent's Micro-Vert in a moment of stupidity 6 months ago, and I've slowly doled it out into the tank during that time, but haven't emptied the whole thing yet (500 mls) only using it cause I didn't want to throw it out, don't think it helps anything. I do use Seachem Reef Plus and only like it cause the LFS's extend their tentacles dramatically when I dose it, twice a week. Mostly I use flake food(!) which my Fungia's and palythoa's certainly relish. I have a Aqua-C Urchin
sump skimmer which I'd never accuse of overskimming, though I'm satisified with it. I dose Kalkwasser and use Seachem Reefbuilder and Calcium alternating in my top-off water. pH is 8.24 with little fluctuation night or day (20 gallon refugium on alternating light cycle) salinity is 1.023, calcium around 425 normally, alkalinity a little low at 6-7, below detect on phospate, nitrite and nitrate. I've had the
toadstool leather practically since I set up the aquarium 8 months ago. Very hardy, even endured a Mela-fix dosing to combat an infection on a coral beauty which killed a similar short-tentacled yellow toadstool. He's my absolute favorite coral. Glad he hasn't grown to gigantic proportions. Though I'd love to frag him and get babies.
