Kalk Slurry…safe longterm?

Don't use it in the tank.
Not sure what your question means... It's it safe in the container long term? Yes.

I personally would not use slurry in my tank. I would get a dosing pump and mix it up let it settle and dose the saturated mixture (clear) at night as top off water.

I’d want a pH controller with a high pH shutoff but kalk is made from saturated calcium and sodium hydroxide as far as I know. @Randy Holmes-Farley already has this setup in a high pH 2 part, I believe, just separate.

Yeah, seems like it could build up over time.

You seen this?

Yes

Yes

Slurry dosing has been toyed with for many years. It was even believed it could lower phosphates, but I don’t know how that played out. I guess now, with cheap dosing pumps, there may be resurgence. Or just do Randy’s high pH 2 part.

why?

I hate that this thread was completely bashed and destroyed, so be warned it is ugly.

I used this technique for a yearish. It works well, but it is a bit time consuming. I couldn't really get to a point where I could spend time to work on automation, but FWIW here it is.

Soda poppin' ... and how to dose infinite Kalk

Ok, how I arrived at this crazy simple stupid idea was kinda like this: It started a long time ago when wet dry filters were still dominant and only the cool kids built Berlins. I had gotten back into the hobby after being in the Philippines and I was absolutetly enamored with live coral, I...

For me it’s a gamble and there’s some unknowns. I’ll let others gamble with their systems before I send slurry through my own. I’m open to anything if it is proven to be safe. I have no problem watching and waiting.

Very interesting video. I need some new beaker’s. What size are those (2000mL)? Are they the tall’s? Do you have a link for those?

I'm not a fan of dosing a calcium hydroxide slurry for three reasons, but folks certainly do it and some are happy with it. I personally wouldn't do it.

1. There's no chance for undesirable impurities to settle out.
2. There is a chance that undissolved and highly irritating particles can land on or near delicate organisms.
3. It is challenging to make the solution of a stable potency.

They are 1000ml that I got off of Ebay.

I later upgraded the Soda Stream with an adapter to a CO2 bottle.

Hope it works for you.
