Vaughn, since folks will be buying this and using your basic idea and you being the main proponent and all......

Perhaps a nice short and simple article about it and the trials and tribulations you have learned upon this path would be appropriate?

I would love to see someone do a dosing calculator for the dilutions.
I can provide any sampling methods, where to get the Volumetric flask and their advantages to measuring liquids toi a high precision and how the methods learned in this, may be applied to making any set of reference solutions for verification of any test kit to a high degree of accuracy. I'll also write a bit about the advantages of going big with volumes and the degrees of accuracy you can gain..
We should all pull together on this one and make this happen.

It'll standardize a burning issue that's been going on for many years, too many.

Giving advice use to be 60-80% game.
I noticed that 90-95% of the issues started appearing to be CO2 related, then I asked why. Folks had 200ppm and had no issues with fish and they have no wood or peat etc added.


This is the last real nail in the coffin, there will always be a small %, maybe 1-3% that will always follow Murphy's law till the bitter end(you know who you are )

But making it understandable and the concepts true benefits is key.
I would like to see a nice standard ref solution make it in this hobby like KNO3, etc.

I know this will help the hobby, make it cheaper, more successful, make us equal all over the world and using the same methods, same chemicals etc for cheaper than any company brand.

There is also a chance that both Richard and Greg will sell the dilutions already done. 500mls of a KH 4 for say 8.99$ and a bottle.

It's really up to them how they want to sell it.
They can dilute or sell the concentrate.

They would have the buy a bottle to go with it, and I know just the bottle, they are like the TMG, the squeeze disperser 500ml/16oz jugs. These are very nice for dosing Traces or other things after you are done with them BTW.

500ml would last you 3.8 years and would require no volume measuring of the dilution etc. Weight is a shipping issue also.

Thoughts?
I want to get this squared away before they start selling it.
Also, the pH color injdicator is certainly not a perfect reagent set that you buy for 6$ etc either, that is the Achillies Heel in the the drop checker system then.
Everything now hinges on that piece of the puzzle. We can assume it's correct, but the range of accuracy is so poor vs a pH meter, I do not think it's an issue personally.

But getting a decent narrow range pH indicator might be something else to check and focus on that's consistent with everyone.

That may be bought in bulk also, you do not need to buy aquarium test kits for that in other words

I suppose they may want to sell that along with the Reference solution.
