DIY KH Keeper reagent

[Dennis Cartier]

Hi it seems I only have 1.0n HCL

Hmm, we could still use that, but the quantities will get small and magnify the errors. Do you have volumetric flasks? If you do, filling a 25 ml flask with 1.0N, then pouring the 25ml into a 250ml flask, and filling the remaining 225ml with RODI. Finally fill a 1L flask with RODI and then pour the 250ml flask and 1L flask into your reagent reservoir.

If you don't have flasks, you can try and do it with syringes. For mixing up reagents for the alkalinity testers, I highly recommend buying a cheap set of volumetric flasks off Amazon. Even the cheap less accurate ones are way more accurate for this purpose.

You can also do it by weight as well. You will need to mix the 1.0N at 9:1 to get it to 0.1N, then proceed with the 4:1 to get it to 0.02N.

Ok I will give it a try by weight

Ok so I have just mixed 225g of ro with 25g of 1.0N HCL, then the 250g of mix with 1l of ro. I will let you know the results

Wow,,I did a test before swapping reagent that was 8.34 dkh. The new stuff was 8.33 dkh..massive thanks..what Strength hcl would you recommend buying from a cost saving point of view? The original stuff mixes 9:1.. I weighed the mix with pretty accurate scales and plastic cups. I assume if I can recreate the measuring accuracy I best stick to the 1.0m? Thanks again

The most affordable would be to use the 1.0N, but most forgiving for measurement errors is the 0.1N or 0.2N.

So the end result is that the KH Keeper requires a 0.02N solution the same as the Alkatronic.

Can I ask what the mix ratio would be for the 0.2N? 8:1?

You can go higher like 5N or something for even more savings, but the higher you go the more effort you need to put into measurement accuracy. I'd stick with 1N or 2N, stuffs not that expensive for years worth of testing. It'll probably go bad or spill or something before you can use it up anyway if you are not testing hourly

That would be identical to the OEM, 9:1.

Ok thanks for you help Dennis

Hi. Where did you purchase the RF KH keeper plus? Ive been looking for one but Im in the US and cant find a dealer.

 

[Dukereefnz]

I am in NZ so purchased from Germany.
The shipping was not to bad.
240vac .... so that's good for me.

Hello Im also looking at buying a reef factory plus. How is ur experience so far?

I've been running one for about a month, best thing since sliced bread was invented

Thank you. This is great news. I have access to conc. HCL, this would save me so much in reagent costs

Concentrated hcl has quite the error tolerance on the actual concentration though and you make it worse when you dilute it, I would stay with titration grade, you can still save quite a lot of money if you get 1N or 2N

Hello, which option is best to choose kh keeper to mix regeants. Link.https://labbox.eu/?s=Hydrochloric+acid&post_type=product What concentration to mix?

 

[gbroadbridge]

Hi everyone, i see there are a lot of diy's for alkatronic, kh guardian etc but none for the kh keeper. has anyone successfully created a homemade reagent with HCL?

Kh keeper uses 0.02N HCl

I've been using a DIY since the small bottle supplied with the unit ran out.
