Physan 20

[ericst11]

I have a friend that swears on physan 20 he says he adds a cap full to his 30gal tank and adds msu . and waters with that everyday his plants look fine . Has anyone else out there used physan. Other then to clean with.

Yup, I use it. But I mix it at the recommended strength and only use it once every month or two. It's good at keeping things generally clean and warding off crown rot. I know that it's also used for keeping algae from growing in big stock tanks, but at one capful in 30 gallons that's probably all it's doing.

I would use but I dont know where to find it

[ericst11]

just look online or at any local hydroponic store.

I use it on all my orchids once a month during the summer when it's hot and humid here in Florida. I hadn't heard of anyone using it all the time.

I know thats why i posted it i had used it but it was to wash my indoor flood table and to flush my pump out and hoses to get the crud out.

Anisa, I carry it.

Following the example of another grower, I have started to add a small amount to my RO tank. He claims that his incidence of botrytis and other fungal infections has plummeted since doing that,

[ericst11]

so he is not the only one that adds it to his watering tank.
