Trying to work out this recipe for making 100,000ppm of Alk and Calcium in each solution. Per litre.
Could someone more chemistry inclined lend a hand?
Cheers!
That doesn’t make sense. What does 100,000 ppm of alkalinity mean to you?
You can scale the recipe to different concentrations by adding more or less water.
Did somebody experienced this issue with standard air tube ? It's not the silicone one but the more rigid one:
This clogged the tube and this jelly stuff, if in contact with coral burn them completely if not taken out after minutes...
I'm really disappointed but a KH drop because of this clogged tube and this jelly is a no go for a stable system for IMHO
Is the sodium hydroxide version the same as 'Randys Recipe 2' in this reef calculator? Its way off, and it mentions it being a pH LOWEREING effect, so I imagine its not the same...
If I'm mixing the sodium hydroxide version, which one should I choose? I mix at 1.5x and have tried both B-IONIC on the list, but those both seem WAY off as well. For example, one tells me dose 555, the other 139. I dosed 75 (just to be safe) into a fresh mix of saltwater and it was still over a full Dkh above my goal.

I tried this new recipe in my tank, but I have reverted to using sodium bicarb (Recipe #2) because the pH went too high with my alk demand (~4dKH/day in a 90-gallon). The high pH led to more precipitation and the Alkatronic detected drops in alk and added sodium bicarb buffer to compensate - but my calcium dropped a LOT (measured approx 220ppm). Caught it early before any major issues (hopefully), but thought I would share the feedback.
The dose of approx 260ml/day was split into 144 doses/day (ie, every 10mins). I wasn't monitoring pH (just alk), so it took me a moment to realise that the rapid increase in alk consumption detected via the Alkatronic was not actually consumption but precipitation. I had removed my calcium reactor for cleaning, so had been dialling in the dose and assumed the increase in uptake was due to the higher pH but didn't account for how high the pH actually was. Upon noticing a fine white dusting on pumps and the bottom glass, I immediately tested pH. With a freshly calibrated pH probe on my profilux, I measured 8.8 pH... Snails were lethargic, sps had reduced polyp extension and my RBTA had shrunk/shrivelled, but my tridacnae seemed fine. I immediately switched my alk solution for the original Recipe #2, and I also gently fed some CO2 directly into the skimmer to bring the pH slowly back down. Luckily no losses seem to have resulted. I am bringing the calcium level back up over the course of the next 7-10 days.
The issue also only arose when I took my calcium reactor offline for cleaning. Lesson learnt!
Yes, but here it's different from what's usually dosed, it's completely solid, i can hold it between my fingers, and it stays like this in the tank before getting broken by the blade of the pumpthe product needs to be added slowly to a high turbulence area. Diluting with more fresh more helps too. The goo is likely magnesium hydroxide.
I have had the airline discolor, but not clog. Mine is into my sump where I have a powerhead pointing up at the surface where the dosing drips into the water to mix it up.
I've all the ingredients but only have 5-litre jugs on hand. Would there be any problem to simply increase the amount of each of the chemicals by 1.32 (3.785 litres = 1 gallon, 3.785 x 1.32 = 5.0 ) and add RO water to total 5 litres?
It's regular air tubing, not the silicon but more rigid one
