You do not want to raise a "blend" of Phyto, usually the stronger strain will win out. Get single strains, probably Tet and Iso.
@ReefLegends is just one state over so you can get the stuff pretty quick I would imagine. Raising Phyto, Pods and Rotifers are pretty easy, most of the time if I lose a culture it is on me and my laziness. You can also do window sill cultures with a north facing window and some frost over the window. (south maybe too intense).
The rigid line is from Depot in the irrigation section, the corks are from Amazon, I use the
Alita air pump to power the bubbles and have air to spare and it is quiet. I used to have 2-3 small air pumps going, but the rate is variable depending on the different levels of water, it was a pain.
