cyano battle lol

[Doug]

Thanks. I added my chemiclean

I think the last time I had cyno was on my sand about 10yrs ago. There is absolutely no reason for it in my 30g, unless its a transfer thing.

I dont know how it just happens for no reason. Unless its related to the eggcrate where it growing. None on the rock. Of course its getting on all my frags, that I blow off several times a day.
