So far the temp has swung from low 40’s to 80. Water temp has hit 90Can't imagine the temp swings here are going to be very helpful for this.

Yeah my DT has lots of nutrients. I haven’t added anything to my experiments. It’s just tank water out in the sun. How green does it need to be?
Yeah I have looked at getting phytoplankton and starting cultures but if they crash you have to start over. Just taking tank water and put it outside seems really easy. I didn’t have the guts to put the full 2 liters in last night so I did 8 ounces. I did notice a feeding response from my green serpent starfish and Scolly went in feeding mode.This was one of my initial mistakes. I thought I could use a splash of starter & it would take off. As it turns out, the recommendation from Mercer is 1:1, but I'm using 2:1 after doing some reading online. Here's a picture of my latest batch.

I got rid of the macros in the outside experiment.
Trying to grow both phytoplankton and zooplankton.Maybe it was covered already and I missed it, but are you trying to get phytoplankton or something else?
I’ve been taking some of this green water and dosing it to DT then take the same amount out of DT back to the outside experiment.At this point, are you using any other nutrient source beyond starting with tank water & the used filter pad?
Should I be adding a fertilizer or pellet fish food?At this point, are you using any other nutrient source beyond starting with tank water & the used filter pad?

Is Miracle-Gro ok to use as fertilizer?We've been at this for about 1 month, & we're finally back outdoors using a 2:1 RO to Phyto blend + F2 from Mercer. We started with 4 oz & harvested 12oz, & now we're using 60oz to get 1.5 gal (on the right). We should be able to harvest in another 5 days.
Here's today's pic after 48 hours outdoors:
I love that it is bubbling. You can see photosynthesis occurring.
Pods eat phyto. So as long as the tub on the left stays lime green, they should reproduce. That's the theory anyway. I'll know in another 20 days. We have a similar thread going in the DIY community if you want to see it from the beginning.

Ok just ordered the f/2. This is my first attempt at growing green water. Things are looking pretty good maybe I don’t need to add fertilizer? Or should this water be darker?I have read that it contains trace elements & might not be suitable for our applications in the long run. Here's a thread on R2R (not much detail but I know there are others of the same opinion). While at the same time, there are others that are having success with it (e.g. here).
For me it comes down to design & purpose. The F2 that came from Mercer w/ the seed phyto is designed for our purposes, & w/o being a chemist, that makes me think it's better over time.
To each his own.
