FAQ

What is the purpose of having two different fitting sizes in one kit? +

The 1/2" fitting is typically used for the nutrient inlet from the bottom-draw pump, while the larger 3/4" fitting acts as the overflow to ensure the tray drains faster than it fills. This prevents accidental tray overflows.

How do the extension fittings work? +

Extensions stack onto the overflow fitting to raise the maximum water level in your low rise flood tray. This allows you to customize the soak depth for different plant sizes or media types.

Can these fittings be used with any hydroponic tray? +

Yes, these utilize a universal bulkhead design that is compatible with most pre-drilled flood tables. They can also be installed in DIY reservoirs by drilling a hole matched to the threaded body.

Are the screens necessary for the system to function? +

While the system will flow without them, the screens are highly recommended to prevent roots and clay pebbles from entering your return lines. This keeps your pump running safely and prevents plumbing clogs.

Is the plastic safe for use with organic nutrients? +

Absolutely, the Active Aqua kit is made from high-quality, BPA-free plastic. It is chemically inert and will not react with or degrade when exposed to hydroponic fertilizers.
