@tribbitt I have some bone cutters and would like a frag if you still have some!

Any frags still available?

It's been a while since my last tank journal update. Life got in the way, we recently just moved into a new home. The tank was a hassle to move, but it got done, haha. Everything looks OK... I sort of think my tank is appreciating the more hands off approach, just water changes and basic...

Kalkwasser is a balanced additive - equal proportions of calcium and alkalinity supplied in a single solution. 2-part additives have a calcium and alkalinity component that are dosed separately in equal and balanced proportions. You were essentially using the Alk component (Soda Ash) of a...

@Coral reefer pointed out that you were dosing Soda Ash without any balanced calcium component, which seems like the most likely reason Alk/Ca fell out of balance. I see you switched to 100% kalkwasser, but are you planning on raising Ca back up with an additive?

Ah, yeah that's probably more likely the cause. I had overlooked that!

Have you checked Magnesium recently? That might explain why Ca and Alk are out of balance...

For what it's worth, I ran a Jabao doser (4 channel non-wifi version) for 4+ years without any issues. I finally replaced it when I observed what appeared to be a power supply issue, the LED's would flicker when it dosed and the motors seemed underpowered and unable to deliver the full dose. I...

Yep.

@under_water_ninja Per your advice I checked the pH of my freshly mixed Kalkwasser and it came out to 12.1. I was following the 6 grams per gallon recipe, but in my case, it seems like I need more to get up to 12.45 (more like 7g per gallon). I should have been verifying saturation with a pH...

I'm dosing 2.2L of saturated Kalk a day, I could go up to 2.4L maybe? My ATO still adds in a little bit of water every day. A fan seems like a good solution to increase evaporation. Would double as a chiller on the warmer days here in San Jose, score!

Thanks for the tips!

I wish I could come in to your shop more often, but I'm down in SJ so it's a bit of a drive for me. A question: Are you able to maintain Ca and Alk from Kalk alone? I find that I am replacing close to 100% of my tanks evaporation with saturated Kalkwasser through a Kamoer dosing pump, and I...

Yeah, while not ideal, I think for some, its simply a matter of convenience. You don't need any extra equipment to add Kalk to the ATO... When I used this method years ago, I also recall it being really tough on my ATO pump, haha. I had to clean it constantly.

I've noticed that as my Kalk reservoir gets low, the pH boost lessens, probably due to co2 absorption from the air. I have mine sealed, but still need a small hole to allow some air in to get kalk out :) I wonder if taller reservoirs with less surface area might work better?

Kalk + CO2 scrubber is the only way I've found to keep my pH close to natural sea water (8.3). Anecdotally speaking, my corals seem to be healthier and growing faster.

I guess it wouldn't be super difficult to add recessed braces like in the video. It kinda distracts from the rimless look, but safety should come first.

What is the brand of super glue accelerator you use in the video?
