Kalkwasser reactor purchase help

Spar · Jul 8, 2019

I am going to start dosing Kalkwasser. My aquarium is around 400g's water volume, so I assume I need a large unit.

I have been eyeing the Reef Octopus KS250 Kalkwasser Stirrer, but is costs over $500. Is a fancy stirrer really necessary? Or is a homemade option of some sort just as good? I would rather pay money for ease-of-use though.

Anyone have experience with this Reef Octopus model or do you highly recommend a different unit?

I’ve used the avast k2 for about a year. I thinks it’s great!

I have the smaller avast unit and its been great. I had to make a small hole in one of the tubes for a syphon break. It has been working for months without a single issue. I go through kalk like crazy, too. I would buy the biggest quanity of kalk you can find, like 5 gallons.

Get yourself the Avast unit, probably the K2 for a tank of your size. It is a very simple and effective design. The best part is replacement parts are fairly inexpensive and readily available from Avast should the need ever arise.

Thanks all, I will grab the K2.

Any recommendations on where to get the best deal on quality bulk kalk?
