How much Phyto is too much?

[DmitryB]

I've started culturing Phyto (just the greens for now; trying my first Rhodomona lens now. Well, second Rhodomona lens, I friend the first attempt with too much light!) Anyway, with gallons of Phyto being made (even if it is just one strain), I've got too much Phyto! How much is too much to dose? I think I've seen @Reef By Steele say they dose up to 2x ml of their gallon volume?? I've tried just one ml of gallon volume for now, but my skimmer (October Regal 200 INT) goes absolutely bonkers for HOURS afterwards. And because I have it draining into a 1 gallon container next to the sump, it FLOODS. Now happened 3 times. Last time I left the skimmer off for 6 hours and it still flooded (I left for work.) So, is it just too much Phyto or does the skimmer just need to be dialed waaaaay down? But then it doesn't do much the other 18 hrs. (This Octo Regal skimmer is a pain in the butt!)

Interested to see what foks have to say. I was dosing 400 mL to a 320 gallon system. I didn't notice that issue with my Bubble Magus curve 7, but that could have been because I wasn't watching closely. I need to harvest and start dosing again.

I culture my phyto so i have no idea what density we are talking about but i dump some random amount in my connected 20+15 gallon system. 1L usually last me 3 wks (cuz i wanna dump them all before going too old) or i can dump it all in 2 wks if i have too much in spare. my skimmer is mounted rather high mostly for air exchange so i never see it going crazy. and i never see any adverse effect with "overdosing"

I don't know if there is such a thing as too much, but when I used to culture my pwn phyto, I never measured how much I added, I just poured. Sometimes I needed space in my fridge and I've had to dump phyto into my tank or else it would have gone down the drain, nothing ever happened. I never noticed anything happening to my skimmer.

In the short term dial it down to dry skim and/or unhook the drain so the liquid fraction just goes back into the sump.
