Holds up to 350ml (~1.5 cups), suitable for tanks 75g and smaller.

Feed pump notes - You may use a verity of different feed pumps for this reactor but there are two popular options we recommend.

Mag drive 3 – This pump is more than strong enough to tumble the biopellets continually and will likely have to be dialed back using the included valve. This will allow room for you to turn up the flow inside the reactor if it were to slow down due to tank debris collecting in the cartridge strainer. This pump option requires the least amount of maintenance and effort.

Maxijet 1200 – This is an affordable option and works well within a few constraints. 
•    It is important to install the reactor close to the water level of your tank/sump to minimize head pressure.
•    It is also important to keep the cartridge strainer free of floating tank debris. You can do this by using the foam maxijet prefilter, filter socks on your sump return and placing the pump in a clean area of your sump 
•    If it does clog you can clean the cartridge strainer as part of your standard maintenance schedule or upgrade the pump at a later date.
