the problem with adding carbon AND an airstone is that you are just pouring money into your tank. the o2 you are adding from the airstone is negating the co2 you're adding. my recommendation? put the air pump on a timer and put it on at night only. since the plants don't utilize co2 at night, it will supplement the tank with o2 for the fishies. the bulb could be part of the equation, but i doubt it. they most likely started melting due to the death of the 2 fish and lack of fertilization. swords are very sensitive to ammonia swings, even if only temporarily. i change the bulbs in my planted tanks annually, but i know people who change them when they burn out.

as far as the pleco goes, you're good to go darlin'. i was under the impression that you had a standard pleco. abn's are perfect for small tanks. they are great little fish. and i'll let ya in on a little planted tank secret: the more plants you have in a tank, the more leeway you have with stocking. the plants serve as a bio filter and allow for a bit of overstocking. so your current stocking level is ok with the swords you have in there.
Ahh, I've just learned so much!!!!
Thank you so much for your time, bill!
I like the timer idea for the bubbler, so if I understand correctly, put the bubbler on at night so the fish get the o2, and turn it off at during the day so the plants get the co2?
I'll get some fertilizer, and no, I don't have access to empty gel caps? Maybe the vitamin store... but I think I'll just buy the root tbs you suggest, I'm not that handy!

I'll let you know how this progresses, thanks again!
