Well over a year ago, I mixed 1 gallon of Metricide 28 with distilled water and got 3 gallons total BUT BUT BUT I can't remember the ratio of how I got that...anyone use glut that can inform me the mixing ratio

Do you really need it?
Metricide has roughly twice the amount of glut as Excel. Just split the dose in half and make it easy on yourself. No need to make it so difficult.
Yes, I do really need it...I use in the place of Excel. Make it difficult? Sorry, that it appears that way to you but this is only my 2nd time mixing the stuff up and wanted to be positive of what I was doing....it last me well over 1 year the first time mixing it meaning its been a good while since I have mixed it.......but okay thanks for your time

I mix 60% glut with 40% distilled water. Dose same as excel!!
What is your glut %? Mine is 2.5%. DO you dose the same (1ml per 10g) since you use 60% glut? I am just curious, not questioning in a bad way.

Edit...I see you said to still dose as you would Excel...thank you Speed

Didn't you just state the ratio yourself? You mixed 1 gallon of Metricide 28 with water to arrive at 3 gallons. This means you diluted it by a factor of 3.

Then, you would dose accordingly (depends on the final concentration of your dilution).

I mix 60% glut with 40% distilled water. Dose same as excel!!
What percentage is the glutaraldehyde you are using? Stating percents is not very good, unless we know the starting concentrations.

What is your glut %? Mine is 2.5%. DO you dose the same (1ml per 10g) since you use 60% glut? I am just curious, not questioning in a bad way.

As mentioned above, 60% glutaraldehyde is misleading; it should be "6 parts" to be more accurate.

I use Metricide 14 which is 2.6% Glutaraldehyde. Excel is 1.5% Glut.

2.6 divided by 1.5 = 1.733

So Metricide 14 is 1.733 times stronger than Flourish Excel.

If you want a 500ml solution of 1.5% Glut, then divide 500 by 1.733 to get 288ml of Glut, to which you would then add 212ml distilled water to bring it upto 500ml total.

Or you can use this handy calculator which does the same thing: http://rota.la/glut/

I personally don't dilute it any more and just use straight Metricide once I figure out the equivalent to Excel just as a reference.
