Physan 20 how much

[yayarea]

How much physan 20 per gallon to clean the system out.

 

[Curb Feeler]

A tablespoon. That stuff is super potent. Might be a good idea to keep it off your skin with dish gloves.


I have a gallon of it, should last me a lifetime.

Are you using that to clean the buckets without plants? 1 Tablespoon for cleaning and 1 teaspoon if using with plants.

 

[AM to PM]

I use 1ml/10gal or 5ml/52gal with plants in system.
