Looks like I got it!

I'm feeling slow and stupid for not recognizing it sooner, it's been rampant for a week now! ACK!

I know there's a million ways to kill it or rather keep it in check...

Does anyone have any first hand info or solutions to treat it?

I'm not able to spend much at all...$20 is kinna pushin it right now but hundreds of dollars of plants are on the line...
I'm headed to Wally World for some baquacil, I know it'll wipe it out but I've no idea the proper (I know I know, I'm using it improperly but it works fine) mix rates or how to achieve a proper concentration?

I know it's a long shot but any help is welcome!
