Dosing Kalk with Bubble Magus on SPS reef

[likefish]

Thought i would ask this question here as you folks are the ones obsessed with ALK and Ca.

I am currently dosing 160ml a day of A and B using Oceans Blend. My mag is at 1460. My alk is still slowly going down if not regulated with water changes.
I want to use Klak again to reduce my demand for A+B solution.

I have researched and cant find a max amount to dose daily with a Bubble Magus doser.

Anyone dosing high volumes daily? I want to dose 1/2 gallon a day = 1892ml.

Wondering if I can trust my Bubble Magus to do this effectively?


My ATO is a gravity fed float valve and it doses kalk poorly due to build up on the float joint resulting in it sticking up and down. I dont trust it and hence need to come up with a better way to add kalk.

Any input or advice appreciated!!

I've tried this and the head wore out after 3 months and needed replaced. It's a cheap replacement but you never really know when it's going to fail. I run the BM doser with 2 part and timed topoff (not float based) using a BRS peristaltic pump. These larger pumps are much better for larger volumes IMO. I have tried Kalk in the past but my evaporation does drift over the year and I'm always nervous I'm going to overdose without realizing it so I switched to all 2 part.

When 2 part dosage gets really high I tend to think most folks switch over to the BRS bulk 2 part mixtures to manage the cost. Much safer, but that's just my opinion with my level of talent.

thanks for the info and the suggestion.

The higher volume BRS doser has poor reviews. It seems that they have trouble lasting a year. I was considering a toms aqualifter as well.

Opinions?

I've got two BRS dosers, one going on a year now, no issues. I didn't leave a review, usually only people with problems leave a review. I bought pump extra hoses because they are a wear and tear item that should be replaced occasionally.

Looks to me like almost 5 stars with 199 reviews.

It's NOT silent though, mine pop when the APEX provides power. You get used to it.

Currently dosing 1.3l of kalk as top off with a MP810 dosing pump
20 times 2 minutes on with a timer, I wired a float switch as fail safe

PH doesn't move much

thank you both for the input.

Seems the more robust dosers are the way to go.

Time to make it happen
