Avast K2 Kalk Stirrer

[Avast Marine]

I have a 150g aquarium but was considering the K2. It's drastically oversized, but not that much more costly for the you build option. Does having the larger reactor provide any conveniences relative to frequency of refills, cleaning, etc?

There really isn't an advantage by going larger here, the refill frequency doesn't change as the kalk is only good for about two weeks inside the reactor before it starts losing potency. The K1 is PLENTY for your system.

I just got one of these. Took about an hour to put together. Really easy and nice build quality. Everything is included, other than some tubing to drip into the sump. That cost me a whole $3.00 extra.

Totally recommend it.
