I did the 1-2 punch
Am now out of Excel
Purchased a CO2
system and hope it works well (Dr. Foster and Smith)
And I think it worked for the most part. I found some of it still green clinging to a plant and took that out but all of it that was attached to the java moss turned gray and is dead I presume.
The only thing I did different was use a different canister filter with its guts out so now I'm worried there may have been some in my other filter, but that doesn't make sense because I would have taken the guts out anyways, and I rinsed the pipes.
