Awesome! It's helpful to know what I'm up against! :)

That sounds like fine thinking. Are there any "brand names" that come to mind that I might ask for at my gardener shoppe when it comes to agricultural lime, or is there a place on the internet I might look? (I must admit I've been tempted to try the "TropicMarin Bio-Calcium" supplement I use in my reef tank, in my planted tanks, but FEAR keeps me from doing so.. Grin).

It DOES grow VERY fast (along with the duckweed).. Since I pumped up the nutrients the other day and added some plants, I'm seeing some serious plant perling (and the bga too! Lol)... If I keep up the nutrients AND the CO2, I suspect I may be able to beat this thing!

Good idea. Discus don't eat anything they can't catch OR fit in their mouths, so I suspect guppies are safe (discus are SLOOOOW). I'll get a few platys/mollies and see what they can do. :)

Well, I pumped up the CO2 pretty HIGH the last few days and the discus have seemed fine really.. I think I was observing them after eating (and yeah, I've been spending WAY too much time at the tank, so they're probably nervous too)..
After I get back in town (leaving in a few days for 7 days), I'm going to try counting the breathing rate and doing some comparisons. I'd like to get over the nervousness about CO2 because I know that it can really help solve the problem (and thus help make the fish healthier too!).
