My VSV is 5ml vodka, 1tspn sugar, 5ml vinegar, and 15ml RO/DI. I'm dosing 2ml/day in a semi-mature 65 gallon tank (few fast growing SPS colonies between 8-12 inches, handful between 2 and 6 inches, a bunch of frags, and a large frogspawn). I started at 3 drops/day then went to 6 drops/day then to 0.5ml/day etc...by week 4 I was at 1ml/day. I stayed there for a couple of weeks then started bumping again. I'm now up to 2ml/day. I've taken a MUCH slower road than most people and my solution is more dilute.
I've put more than 6 months worth of food in my tank since I started all of this. I am floored that my NO3 and PO4 levels are still so low. I actually started this experiment believing it would fail and I would have to return to a nutrient starved Berlin system.
My DIY Amino Acid supplement is...ahem...suspect at best. By RHF's, Mesocosm's, Genetics, or MCSaxmaster's standards, it's a no-go. That's why I want to replace it with an off the shelf product. I'm not really getting any darkening. If I overdose I will see a little extra algae on the glass the next day but that's about it. How do you like the Brightwell AA's? Have you found your tank's maintenance dose? If yes, can you describe?
I've also been doing a DIY bacteria culture kind of like Scoob's at UR (
http://www.ultimatereef.net/forums/printthread.php?t=211460&pp=40). His thread is pretty entertaining and worth the read even if it's just to catch his candid writing style. My culture is definitely growing some funk! I have a dish with a small rock. Every few days I add a few pellets of food, a few drops of VSV, and a few drops of AA's. I then pour about half of the volume into the tank on a ~nightly basis then refill it. I'm thinking of it more as a food source for the corals though rather than bacteria inocculations since I'm not dosing with any proprietary bacteria sources. So far, I have no reason to suspect my tank to need anything of the sort. Scoob's tank seemed to have the often speculated but never verified 'mono-culture' though (I wouldn't have believed it until I read his thread).
Jon, I hope you're in Ireland drinking a Guiness Red! Please chime in when you get back!
