Yeah, an ATO should def help with that, but we might come up with something else to keep it perfectly stable... I'll roll out here soon enough (less snow maybe, UGH!) - need to see the tank anyways bro!

You can dose the whole vial. There was some talk on another forum (don't remember where, RC maybe?) where Prodibio noted you could stick the vial in a Potato (just to keep upright) in the fridge and save it for "X" amount of days (a week I think). Check that Prodibio thread I linked you in a PM...

Dose into a high flow area in your display. I don't turn the skimmer off, but I wouldn't recommend dosing right in fornt of it... it will either kill the head or skim it out!
