Can’t keep Alk up

[Dennis Cartier]

The problem is I can’t get it to 7 lol. I’m already dosing about 48mL daily via doser. Trying to add 48 more to get it above 7 currently

Just a thought. Have you checked the calibration of your doser recently? Perhaps it is not dosing as much as you expect it to. If your doser offers a calibration function, it may be worth a try.

I for sure can check this out. I do know I just dosed 60 mL which is 1.5x the amount usually dosed on top of what I’m currently dosing on my doser and it didn’t move any. I’m going to wait another hour and test again…

I think someone ripped me off with my alk maybe? I bought a couple 3 gallon buckets of esv that a guy said he used a little bit of and now didn’t need. Maybe he over diluted the alk as there was much more gone from that bucket? Why I was curious if I could test the potency of the alk solution @Randy Holmes-Farley

OK, we can use a calculator to determine that 0.89 ml of B-ionic alk part added to 1 L of tank water or RO/DI will boost the alk by 7 dKH.

So try something like that and then test it.

Reef Chemistry Calculator

(note: the calculator rounds 0.89 mL to 0.8, so to get more significant figures, do the calculation for 10 or 100 L and divide by 10 or 100 to see the proper amount needed)

Spot on rodi to 7dkh after adding .8mL to 1 L of water. So it’s not diluted which means it has to be precipitating out.

Or otherwise being consumed.

No way it’s jumped from roughly 30 mL daily to over 75mL daily..I added 60 mL on top of my daily 30 and it hasn’t moved at all. My calcium is reading higher than the test can test also..

If it is precipitating, that would lower calcium as well, no?

I would assume so..

What are you using to test dkH
and CALC with?

 

[JonEB]

Do the corals appear stressed?

Salifert for years

Corals look fine

Do you have anything to get a secondary reading? Nyos, Hanna, Aquaforest?

 

[JonEB]

You could set up a gallon of premix and test the potency of the ALK product your using. But I would suggest a secondary testing method to make sure you have at least 2 reference Points.

Did you read above? Tested potency and is accurate with what it should be. I also test my water change water to confirm it’s in range with what’s expected with a fresh mix. All lined up

Missed that comment

I had a similar issue a year ago but found it was my test kit. The reagent was contaminated.

All good ya I’ve confirmed the test kit is accurate.

Have you tried stopping the CALC dose for a day to see how much it falls?
