Pro thought: drop a thin glass plate into the bottom of the container!! The spinning stirrer will eventually eat though the bottom. A plate (or extra thin bottomed drinking glass from a thrift store) will remedy that. :) Happy Reefing!

I've been waiting for this video. Thanks

Cool project! Always enjoy your DIY stuff. I was holding my breath when you were running that tap into the acrylic. Great job.

Love your DIY projects 👍

Awesome DIY Dev!!💯

great video, how would you calculate how much kalk to dose for your own tank?

I did exactly the same with an Avast reactor. Same stir plate and all. I went to the parts store on Avast and got their K1 tube, bottom, and union. I then 3d printed the lid. Has been working fantastic for about 2 months. Also, drill a small hole in the top of that elbow to break siphon.

Hey Devin, another nice vid bro. I wanted to get your thoughts on Kalk dosing VS BRS 2 part. my tank is a LPS dom. mexed reef in a red sea 650P (another peninsula fan here.) new to dosing have not dosed before and was thinking of getting on the kalk wagon via the versa if I can ever find one. if not was thinking the red sea reef dose. my goal is easy, clean and simple. was thinking the avast kalk stirrer but not sure I fully under stand the benefit of the stirrer? would not the kalk once mix to max saturation not need to be stirred? then you could dose your dialy amount from that?

Did you.get any where with the vinegar dosed CalRX?

What frequency do you dose?

Problem with those cheap stirrers is that they use a brushed DC motor that has a potential of only lasting a short period of time (brushes wear out). Best option is to find a stirrer that uses a brushless motor. Another thing to consider for longevity is finding a pill that has a ring in the middle so that the only part in contact with the bottom plate is that ring. It will reduce wear over time.

Awesome Dev! You mind posting your Apex program to oscillate the stirring intervals?

I guess I dont need to try this if i got that geosreef right?

I did this a while ago, 1. Sometimes it dosent start to spin. 2. When it spins it slowly drilles a hole it the bottom of the conteiner

Nice project! If I am dosing Kalk and use the original output that it came with it, I wouldn't have to drill a hole on top right?

What do you think of connecting this to the output of a calcium reactor to increase ph

So how has it been working? Thinking about making one. I just ordered the dc2 and I have a magnetic stirrer

What happened to the Icecap Kalk reactor you had? And if you still have it, is it still running good?

Is this magnetic stirrer strong enough to stir through a plate? My reactor has one little plate above the bottom.

What is the name of that reactor I can't find it anywhere

I did something close to what you have but I have it dosing the slurry. Have you noticed any kalk Precipitating out?

Doesn't this mess with your calc reactor's alkalinity dosing rate?

Were you doing 2 part dosing before the kalkwasser? How did you transition over without a alk spike? Thanks

Dev.... Are you doing saturated kalk or the more concentrated kalk slurry?

What happened to the icecap?

a little credit would of been nice

It's not worth it alk will go up also
