I would try making a For Trade or Random Act of Kindness (RAOK) thread in various forums showing detailed pictures of your current disk and a list of plants you want and some reasonable amount of time you need to make the disks, if you can't make them before hand. If any takers you make them say over the next weekend. I'd highly suggest doing this at Aquatic Plant Central as the member base and plant quality/accuracy of species is excellent in their very active FS/FT Forum.
No offense taken plant monster! Just a couple cents for whatever it was worth and the sake of discussion amongst monsters and people who like plants The below is in the same sprit
Agree with the majority of your points here in your most recent post as well. I
A little of both. I use (and prefer) very high light/growth/CO2, and find I do have to increase CO2 (and dosing) over the months to control algae. Also, when I see any issues in plants and think I need to adjust some nutrient but no desire to isolate it, I tend to adjust CO2 as well as the likely nutrient, since CO2 is a pretty good bet (~40%) to be the root cause of the issue. I believe this to be at least in part because my plant mass in my tanks tend to change drastically over any given, say, 3 month period, and in part because I use sunlight from a South facing (Northern hemisphere) window, so my photo period also changes.If you were adjusting your CO2 to try another flow rate, no problem, if you are adjusting the flow to maintain a level, then I would see that as a deficiency in the needle valve (likely) or the system.
I like dynamic tanks and my CO2 reflects that
