Great info. I am going with 25% then and just use 120ml instead of 60ml for a 2L bottle of "excel" like. Boy, I am glad I asked you about the shipping. Thanks a lot.

Hi barbarossa4122,

I usually call my order in and specify "no special packaging" otherwise they will want to thermally protect the ingredients so it says good for your electron microscope. They will want to know what you want if for, just tell them it is used as an aquarium additive. They will assign you a customer number and you are good to go. BTW, Credit Cards only; no PayPal!

Hi Seatle_Aquarist,

I received my 450ml bottle of 25% bio grade glut the other day ($26.00 shipped) and would like to make a double strength (3%) Excel like solution. Will 120ml of Glut to 1L bottle do it ?

Hi barbarossa4122,

You are correct, 120ml of 25% concentration Glut combined with 880ml of water will make 1000ml of 3.0% concentration solution (2X Excel strength).

BTW, your 1000ml of mix cost you $6.93 including freight. Typically a 2 liter bottle of Excel costs about $30.00 from the big on-line stores plus $8.99 shipping. Congratulations, you are saving about 61% and getting it in the concentration you wanted!

Hi Seatle_Aquarist,

Well, thanks to you I bought 25% Glut. Metricide worked good also but, I'll more happy with the Glut since I can manipulate more the concentration of the solution. Great help, thanks.

Whats the shelf life of Metricide? Does it go bad after 14 days?

Hi DvanK,

MetriCide is typically used to sterilize heat sensitive medical devices and instruments. For example, if you were a dentist and needed to sterilize instruments you would pour some Metricide into a container and add the instruments for 20 minutes. The MetriCide could be used for up to 14 days and then would have lost most of it's sterilization properties and would need to be replaced.

My experience has been that as long as I store my Glut in a cool, dark, location and it remains viable for well over a year after I have opened the container.

Thanks I was afraid that It would loose its properties after 2 weeks or so.

Is there a way to determine whether it's viable other than observing whether it seems to be having an effect?
