Curious what others do for dosing phytoplankton. Daily, weekly? Volume of dose and volume of tank. My picotope has about 4 gallons total volume (including the HOB refugium) so I've been dosing .5ml per dosing period (every other day) with pumps off for 15 min during dosing. I used the label to figure out the math which recommends 1ml per 10g, rough estimate. I have nothing in the tank, although it was live to begin with (live rock/live sand) I'm still waiting the 7-8 weeks to introduce inhabitants. Since the end of week 1 the only thing that has been inside was Chaeto which brought tons of pods. The thought was I have 7 weeks to let the pods take over the tank before a predator is introduced. Feedback is greatly appreciated. -Tony
