Apologies, if there was confusion. I am referring consumption over 24 hours. 5dkh over 24 hours based on dosing amount.@Blaise006 Wait is your dKH swing 0.5 or 5? Your first post stated 5 but then you said it swings .5-.8 which isn’t really concerning.
Trident controls dosing at 10%. Outputs are in different sections of the sump. Calcium is dosed in equal amounts.To me something seems off if you have to dose that much when the lights are out. Are you using the trident to control the dosing? Are the outputs of the Alk and Calcium near each other? How much Ca are you dosing?
I checked last night. Didn’t see any precipitation like that. Maybe I just got a weak batch of ESV.Did you look in your sump where the dosing tubes actually drop the Alk and Ca? One time my consumption rates started increasing more than I could explain and when I looked in that part of the sump (had to kinda climb in there to see it well), I found that it was forming a little calcium carbonate island stuck to the wall and immediately precipitating out like 30% of the dosed liquid before it could get to the water and disperse.
Is your coralline growing like mad in the tank? Also do you have a clam or added a clam recently?
Of my ESV-B Ionic?What's the alk level of your solution? Wonder if you've ever measure it before.
Calcium is dosed at the exact same amount as alk. Stable at 475 +/-15. Trident reads high but is stable.How’s the ca and mg dosing rates and levels?
I’ll dilute some to see if I can get it within range for a Hanna checker to double check.Yes, of the ESV-B Ionic.
It's conceivable that the amount of 2-part seems high but it might actually be what your tank is using. I remember talking to Alan when he had a 12" squamosa in his 100 gallon cube with no hard corals and he was dosing 400 mL/day just to keep up with it. With roughly 30 frags, plus a 6" clam, plus the amount of coralline in the tank, it's plausible that 180 mL is needed. You might even need to dose more depending on how much the alk is swinging daily when your lights are on.
How many gallons was the tank?I had a rugby ball sized chalice which was almost eating 100mg/day by itself of brs alk solution, so it isn't out of the question.
My 168 I have nowHow many gallons was the tank?
