Hey guys please help I don't now if I should get the stirer or the reactor with the power head. Any ideas of a good brand? I been reading ups and downs with the brands and I don't know what I should get . The stirer or the reactor with power head. Please and thanks for all responses

If you mean calcium reactor vs calcium mixer(stirrer?) they are a bit different.
A calcium reactor resolves coral gravel/skeleton and add calcium, magnesium, carbonates and other stuff to the tank.
A calcium mixer is filled with calcium hydroxide, which increases KH and pH mostly, and add a little calcium.

Always Making Something
The terms kalk reactor and kalk stirrer are used interchangeably. I've never heard of a convention that kalkwasser devices with a pump must be called "reactors," while devices that use a mechanical stirring arm must be called "stirrers". Personally, I consider them both to be the same thing: they both keep the saturation of lime water at 100% at all times, regardless of whether they use a pump or mechanical arm to stir.
Personally, I would go with a reactor that has a manual stirring device. The lime water doesn't need to be agitated aggressively to maintain 100% saturation. In general, it's best to keep the mixing as gentle as possible to avoid working in any additional CO2, which encourages calcium carbonate to precipitate and wastes calcium hydroxide powder. In a properly sealed reactor, there is probably not much difference between a stirrer and powerhead, but I would still go with the lower-tech stirring option.

Okey, sorry. In Sweden they are called Kalk mixers
But it's the same as stirrers. And calcium hydroxide is the powder to make kalkwasser. I've only used the stirrer, so can't say anything about the one with a powerhead.
