A great new way to grow macro algae and add a refugium!

Now you can easily reduce organics/nitrates as well as grow natural foods (copepods, amphipods) for your fish! The reactor can simply sit underneath your aquarium (extra tubing may be required), next to your aquarium or next to your sump: taking up very little space.

The package includes an AquaMaxx Media Reactor, 5` of vinyl tubing, water pump and a high-output Accel Aquatics LED strip. Simply wrap the LED strip around the media reactor and secure it with zip ties. Place chaetomorpha, caulerpa or other macro algae into the reactor and install it like you would a regular media reactor.

The close proximity of the high-output LED strip gets as much light to the macro algae as possible and quickly grows the macro algae. As macro algae grows, it will consume nutrients in the water. Once you harvest the macro algae, the nutrients are then removed from your system.

The macro algae in the reactor also makes a perfect safe haven for copepods and amphipods to reproduce: providing a natural food source for your aquarium.

Installation Instructions

1. Place the reactor in a location where the outlet is higher than the sump. The quick connect outlet is where the kalkwasser will drip from and typically hung over the sump in a high flow area away from any pumps. The output must flow downhill to the sump area.

2. Connect the feed pump from your top off container to the Kalkwasser reactor with 1/4 RO tubing. Peristaltic pumps are preferred due to the high level of accuracy and anti siphon characteristics. (If you are using a peristaltic pump then skip to step #4)

3. If you are using a feed pump like Tom’s Aqualifter then the input tubing should be placed in your reservoir with RO/DI water. Connect the outlet of the pump to a short piece of 1/4” tubing and install a tee fitting with one end securely mounted several feet above the water level of your top off reservoir and the other going to the reactor. The tee is placed in the line to create a siphon break. You may also use a small pump such as a maxijet modded with a fitting on the output to feed water to the reactor. You will have to use a check valve in the line to prevent any back siphoning into your reservoir.

4. The Kalkwasser reactor should be filled 2/3 of the way with RO/DI water.

5. Add enough kalk powder to fill the reactor with approximately 3/4 – 1 cup of kalkwasser. The idea is that the twin blades create a slow motion that gently disturbs the kalk in to solution. (Too much kalk will place stress on the motor and can cause pre-mature failure) Allow the solution to settle for 15 minutes prior to turning the reactor on. Now you are ready to plug the reactor’s transformer into a power source and begin to dose saturated Kalkwasser to your aquarium. The stirrer should be set on a controller to run ever 2 hours for approximately 10-15 minutes. Do not run these units 24/7.
