Hi all,
So I went out of town this past weekend and had my friend look after the tanks. She just fed, dosed ferts, and checked for any obvious catastrophies. When I cam back, I had snails, an injured yo yo, and a TON of BBA on my drift wood.

The snails went away once I fasted my fish for a day. I fugure the yoyos were just being fed too much to have an appetite for snails.

The yoyo looks like my bichir took a chomp at him. Both of his sides are brused and red by his gills. The shape and placement of the wound suggests "bichir jaw". So I took out my Carbon and dosed the tank with "metaflix"? (the bottle is at home, but I am fairly certain that is what it is called). It is supposed to help promote the healing of wounds. I can't put him in my other tank for healing because 1) it is WAY colder than the one he is in now and 2) I have a mystery snail in there that would get eaten (the snail can't go in the main tank b/c there are yoyos in there, too).

The BBA is mostly on my driftwood, but a little is on the ludwigia, swords, and madicascar lace. I say it is a mystery b/c the CO2 is constant as it is a pressurized CO2 system on a timer to shut on/off. The circulation shouldn't be an issue either. I have a pump (level 1) that creates circulation throughout the whole tank. All plants are gently swaying and there is good surface movement.
I dosed with excel to see if that will clear it up, but I don't wanna push it with the excel b/c I don't know which plants can tolorate high doses of it. A direct dip in 2:1 water to excel solution killed my anubias and swords.
Here is a list of the plants in that aquarium:
Madigascar Lace-2
Ludwigia (red)
Aponogeton Ulvaceus -2
Silvermist Foxtail
Rotala Indica
Melon Swords (red flame and regular)-4
Japanese Rush? -1
Anubias, petite nana -2
Narrow leaf chain sword-4
Java Moss (only a pinch)

Also, whenever my Madigascar gets any algae on its new leaves, the new leaves are "stunted" and don't really grow anymore.

My questions are:
Has anyone had trouble with any of these plants when overdosing excel?
Anyone think the BBA is from too many nutrients?
Can anyone pinpoint the cause of the BBA?
Should I withhold regular ferts when dosing excel?
Advice/ insite on the Madigascar issue?
Is there anything bad that would result from the 'excel + medication + no carbon in the filter' conditions?

Any advice on the situation?

Thanks! :D

Okay, so I got my drop checker in the mail yesterday (only took 16 days from when I placed my order lol). It indicated that my CO2 is too low (blue color in the ball). So I will mess with the CO2 regulator today to get my CO2 level up.

The yo yo is healing up pretty well (all things considered). I added 8 barbs to the tank yesterday (1 cherry 3 goldens), so I put the carbon back in. I think I'll do a 10% water change today, too.

With the barbs and increased CO2, my BBA should clear up (fingers crossed).
 
BBA cleared up pretty well. I went in with a toothbrush and removed most of the BBA myself. Apparently my bichir became a magician and made 7 out of 8 barbs disappear.....overnight! Twenty bucks worth of feeders lol. Guess I'll have to buy fully grown ones next time.....

My Co2 is optimum as of now and the tank is pretty much algae free!
Guess it was just CO2 problem.......
