Active Aqua Extension Fitting, 1", Pack of 10

Raise Your Flood Level for Taller Containers, 1in

Different container heights need different flood depths, and a fixed-height fill/drain fitting forces a grower to either compromise on flood depth or rebuild the table's plumbing for each container change. The Active Aqua Extension Fitting raises the fill/drain level in a flood-and-drain table, letting growers dial in the flood depth that actually matches their container height instead of a one-size-fits-all setting.

This 1in extension fitting is sold in a pack of 10, enough for multiple tables or ongoing spares.

Key Features & Benefits

• Raises the flood/drain level — lets growers set flood depth to match container height.
• 1in extension sizing — matches standard 1in flood table fill/drain plumbing without an adapter.
• Pack of 10 — covers multiple tables or repeated depth adjustments across a season.
• Simple add-on installation — attaches to existing fill/drain fittings rather than requiring a full rebuild.

Who Should Use This Extension Fitting

Growers running taller containers on a flood table — or switching between container heights across grow cycles — are the fit for this extension fitting.

Frequently Asked Questions

What does this extension fitting actually change?

It raises the fill/drain level in a flood-and-drain table, which changes how deep the flood cycle reaches before draining. That lets you match flood depth to your container height instead of using a fixed default level.

When would I need one of these?

Use it when your containers are taller than what your table's default fill/drain level was set for, since a flood cycle set too shallow won't reach enough of the root zone. It's also useful when you're switching between different container heights across grow cycles.

How does it attach to my existing plumbing?

It attaches as an add-on to the existing fill/drain fitting rather than requiring you to rebuild the table's plumbing from scratch. Exact attachment specifics depend on your table's fitting layout.

How many come in a pack?

Each pack contains 10 extension fittings. That's typically enough for multiple tables or repeated depth adjustments without a separate reorder.

Can I combine it with a screen fitting?

Yes, growers commonly combine an extension fitting with a screen fitting in the same flood table setup, since they serve different purposes — depth versus media filtration. Active Aqua also sells a combo kit that bundles both.
