The right control box, first time
This is the DC version control box for the AA / Fish R Fun Green Killing Machine 9W UV system (GKM9W), fitted with white plugs. If your unit has stopped running and the plugs on your existing control box are white, this is the replacement you need.
Not sure which version you have?
The GKM9W control box came in more than one version, so check before ordering: this listing is the DC version with white plugs. If the plugs on your control box are black, this is not the one for your unit, and you'll want the other version instead. Match the plugs and you can order with confidence.
Why replace the control box?
The control box is the heart of the Green Killing Machine: it drives the 9W UV bulb that clumps together the free-floating algae behind green water, so your filter can catch them and your aquarium stays crystal clear. When the box fails, the UV falls silent, and green water follows. Swapping the box revives your existing system at a fraction of the cost of a complete new unit.
Key Features
- Replacement control box for the AA / FRF Green Killing Machine 9W UV system (GKM9W)
- DC version with white plugs: please check your plugs match before ordering
- Restores UV action against green water algae
- Economical fix: revive your existing 9W system rather than replacing it
- Control box only: UV bulb, internal unit, and other parts sold separately
Check your plugs, order this box, and your Green Killing Machine is back on green-water duty.
