Thanks.
Its Glutaraldehyde 50% i have made into Glutaraldehyde 1.5%, by mixing it with distilled water.
I think i will start with 20ml and take it from there.
Also i have read certain plants do not like Glutaraldehyde, i have a feeling my Giant Vallis may get killed.
Has anyone had this problem ?

jacko5 Ok guys, i have just made my first batch of glut.
1.5%.
For my first dose do i put 20ml in like i will every day ( i should do 17.5ml really but i have upped the dose a bit ) or do i put in 80ml ( i should do 87.5ml but i have lowered it a bit as i do not do a 50% water change ) like i will do on a water change ?
Thanks.

My current bottle of concentrate, which I store in our downstairs refrigerator (proper marked at "Poison"), is almost empty and it is just a potent as it was when I purchased it in November, 2012. When I make up the 1.5% concentration I try to use it up in a couple of months and I store it in a dark cabinet at room temperature.
Thanks a lot for that.
I will get 1 liter then.
Hope it lasts me 2 years and be Ok in that time.
I want to use it as i have just got LED lighting and am getting a lot of hair algae, i have adjusted the lighting now, turned the power down.
I am hoping this will help to keep the algae in check as well as feeding my plants.

Actually 26 for 1 liter of 50% concentration glutaraldehyde delivered is a very good price. 1 liter of 50% will make 33 liters of 1.5% (Excel strength) mixture. It stores in the refrigerator for over a year without losing potency.
Thanks for that.
When you say it stores for 1 year, do you mean the glutaraldehyde 50% after its first opened ?
Or the batch you make up from the glutaraldehyde 50% ?
I think a 1 liter bottle of glutaraldehyde 50% will last me 2 years, so it may only last 1 year when opened.
Really no use in buying the 5 liters.

UK peeps on here let me know if you find a cheaper option for glutaraldehyde 50% , thanks.

jacko5 Thanks.
Also for android phone users who want to calculate Glutaraldehyde mixing, look at this great app,

sowNreap Pro-Advantage by NCD (formerly called Omnicide) is same as Metricide just different name .. maybe search for either of those names. It could even be called something different in UK.

But as mentioned don't get the 28 day of it either .. same exact thing as Metricide 28, it has surfactants & rust inhibitor.

I guess this is not good to me ?
No, the 28 has soaps (surfactants) added to make it last longer as a disinfectant - great for the tattoo guy, not so good for your tank. The 14 has no soap added, and if you find some DON'T use the little bottle of "activator" tha t comes with it - you just want the main bottle.

It looks pricey, but Amazon UK has both Cidex in quarts and Metricide in gallons. See if you have a hospital supply company anywhere near you (or on-line with in-country shipping)
