House of Zwaan No air in res.

Morning guys, anybody here grow with Huse of Zwaan Aqua Flakes?
They say not to airate the res which freaks me out a bit.
I guess airating can cause the nutes to react badly. Anybody have info on this?

I was told it was a misprint, and that it will be fixed shortly. Obviously that doesn't make much sense. Appears it was one of many errors and inconsistencies that occurred during the Dutch to English translation. Let me know how you do with this line, as I'm just trying it out myself in Hydro , Aqua Flakes and Soil - Peace
