How much dkh drop warrants dosing?

I killed a tank doing this.  I thought everything was dialed in but I ended up spiking the Alk.  Total nightmare...

Did you remove significant numbers of corals, and forgot to slow down the doses? 

 

I would think that the alk consumption would continue to rise with the growth and coral biomass, thus require gradually more/higher dose amounts long-term.

 

The reason I'm asking is because, I'm adding nearly 20 ml each for Reef Fusion 1 & 2 daily for my tank.  And I don't anticipate any slowdown in growth, so just wanted to know what to look out for.

Coming soon: Apex Ca/MG/Alk control. Wil revolutionize the hobby for those who can afford it, I am guessing retail $799 plus ~$30 in monthly reagents. Automated titrations, and then your apex can control the specific doser to bring up the parameter. Craziness. The technology in itself for the titrations is not new- see Hanna Checkers- but the automation (monitoring hourly) is HUUUUUGGGGGEEEEE.

Already released:

 

KH Guardian. $549, monitors Alkalinity. Can be connected to controller to add on automatic alkalinity dosing.

I would need a brand new apex since my older 'lite' version won't be supported. Boo! The new one is so UGLY too. 

 

I am not a fan of early adopting anyways though... I mean if this thing messed up testing.... it could crash your tank  Want to make sure others are the guinea pigs 

 

I wonder how many tests the $40 reagent gets you.

 

I would rather just buy one to test just alk at 1/3 the price... someone make that....

dKH and Ca are two things I have not measured in my tank for a while. I'll measure over the next week for fun and see what it is doing in there.

Markalot, with a tank your size, will you be ordering an Apex Trident once it gets released? (Or once we see that it gets reviewed well).

 

Your daily drop can be calculated (without killing all acros  ) pretty easily:  concentration of supplement * volume

 

No, I won't pay that kind of money to monitor KH.  $300 + $50 a year ... maybe.  I doubt we will see that price for a long while.

Kh+Ca+Mg on the apex trident. Plus salinity probe on the apex... reef testing porn!

No...I just basically got cocky....used BRS two part...overshot the alk.  I aslo didnt truly respect alk. or how important it is, tbh.

On my current tank, I do not see consistent consumption all the time....I see it most of the time, but sometimes I see days where if I would have dosed, i would have shot past 9.  I have no idea why this is, or if it is normal...but its caused me to test more frequently than I might otherwise.  (it could just be the _+ accuracy of the tester too)

He's referencing the Hanna checker and He's not alone.

 

Mine has been nothing but problems. Got it tested (store tested it once) says it's fine. It's a user issue.

 

I find that funny.

Worked perfectly well for 2 mnths then goes to off and on (i mean one accurate test then unable to test at all 5 mins later) that's not a user issue.

If I was the cause, the problem would happen every time.

 

So I was gonna buy all Hanna checker and now I will buy none.

The customer service and warranty process with the company is not good at all.

 

The checker is over priced for a 6mnth warranty, lack of service, and faulty products (there are many out there)

 

I'll stick to my tried and true salifert.

There seems to be a lot of complaints around about Hanna. I got the phosphate one but not thrilled with it, and won't bother with any of their other ones. Calcium one seems to have the biggest complaints.

I myself noticed through testing that consumption rates change.

 

My tank uses less now than it did a year ago. I have more sps and lps. 

If I had not been testing so frequently at the time, I would have ended up dosing too much.

Exact experience I had.

 

Consumption is not consistent.

 

I have gone days with no consumption and then 4th day after waterchange, there's a drop.

 

Other times I have seen drops daily or every other day.

 

I think corals don't use up the same amount all the time which makes dosing an issue.

Yup. I heard good things about the alk and phos.

 

Then I started having issues with my alk checker. I specifically looked up the issues I'm having and voila- lots of complaints found.

 

I was going to get the phos checker. I'm not wasting another $90.

 

It's obvious the company doesn't expect them to last longer than 6mnths- that's the warranty on them. 

 

To try to get anything done with Hanna was a headache. 2 weeks of emails between them and the store and calling in.

Big fan of my Hanna....seems consistent so far and makes me keep my Dkh at the top of my mind....just trying to balance out your criticism

I agree with everything you said there. Consumption changes as frequently as daily, that’s also why we need to give ourselves some breaks regarding chasing the exact numbers. 

Just wanted to add a note though, while it matters what and how many corals You have, what matter more (in my opinion, and I could be wrong here) for consumption would be the growth rate. If you have no visual skeletal growth, the corals will thus consume less calcium and carbonate in the system.

Its not the accuracy. I can't even use it anymore. I can't get to the point pf adding regent 

 

I had a positive experience and recommended it- when it worked. I expect a tester of that cost to last more than 2 mnths.

 

It was disappointing

 

Most ppl are not going to speak positively about a product they aren't happy with. 

 

You wouldn't.
