Hey guys,

Running a system with approximate volume of 300 gallons and up until now have been pH'ing personally. Would like to step up to a pH controller and have seen a lot of good reviews on Bluelabs products.

Strangely, the the BlueLabs pH controller lists a maximum res size of 200 gallons and I am wondering what that could even mean.

Has anyone used BlueLabs pH controllers for larger ressys successfully?

Thanks

Mr Slipps
