I have a few of these bugs and was looking at buying some Bioguard Backup to kill them in the event they get bad like they did last year. But, its expensive and I would need alot of it. I read in a previous thread that any algaecide with 50 in the name would do the same. So, that being the case, is this a good substitution?
