kulk reactor mixing question

[customcolor]

i have an idea on how to build a kulk reactor, but i was wondering how do make it so that the stiring power head is not running when its dosing so you dont put undesolved kulk into your tank.

Well, this isnt a problem usually because the kalk mixer should only run on a loop which makes the bottom 1/2 of the reactor full of kalk... leaving the top clear. This is where you draw your water from.

Many people put the mixer on a timer that also controls the ATO so that the ATO is off when the mixing pump is on. Or just make sure that your system will never do more than a small amount of water at a time so even if it gets some undesolved kalk into the tank it is not enough to cause a problem.

now how do i keep it from getting to the top half.

Make it tall enough and dont use to large of a mixing pump.

do you need to use fresh water or can u use water from the sump?

Fresh, kalk and SW do not mix.

A kalk mixer is usually plumbed to that the intake for the pump is about 1/2 way up the skimmer height, and the outlet is at the bottom. So the kalk mixes up from the bottom to the pump intake... but not much above this. You can literally watch the kalk in the reactor as it makes small waves inside the reactor... like oil and water. If the kalk reactor is done right, you should never have the 'cloud' go much above the intake of the mixing pump. I never do. This is also how kalk reactors are sized. The 'always clear' half of the reactor should be enough volume at all times to cover the volume of water that a dosing pump or top off would use... so cloudy water never gets into the tank.

how far would your input line inside the chamber go down to. would it only go to the inlet of your mixing pump?

[hahnmeister]

The input line can be at the bottom of the mixer... the output though should be in the top half.

sounds good now just gota find some stuff for the idea and go for it
