I am planning on ordering Metricide 14 to replace the Excel dosing. Right now I dose 10ml/day of Excell in my 55g. How much 100% Metracid do I need to dose to match the Excel dosing. Also do you know if it's safe to overdose Metricid a little? Thank you.

10ml/day?

I use 5ml/day on my 55 gallon. I really dont think you wanna use 10ml/day when using Metricide 14 cause its a little stronger.

Bump to top.

Thanks Gate :)

Also for anyone else reading the thread there is some good info here as well.

I dose 7ml daily - full strength in my 55

Just a heads up for those who are interested in purchasing Metricide 14: Dealmed.com seems to have lowered their price by $2, making the total $22.14 ($17.15 for one gallon and $4.99 for standard shipping). Not sure how often the price fluctuates on this product, but I haven't seen it lower than this over the past few weeks.

I paid $ 18.95 + $ 9.95 shipping on March 11th. Still way better than buying Excel. Just checked their website , darn I did not know about the $ 4.99 standard shipping.:icon_cry: Next time I'll be more careful. :)

Thanks for the heads up dj2005.

Yup, I pointed out the cheaper shipping last time. Gotta check that drop down!

Pretty much, if I figured this correctly, you can just multiply whatever dose you'd normally use for Excel by 0.6 and get your Metricide-14 dose? Seeing as Metricide-14 is 60% stronger mL per mL. 1.5% for Excel, versus 2.5% for Metricide (1.5/2.5=0.6). Or at least get you pretty close to whatever you want to dose. I don't feel like making my own Excel, would rather just dose it straight.

Just ordered myself some. Ran out of Excel yesterday.

I ordered a gallon last night from dealmed.com for $22.14 shipped.

I am good for 378 days of dosing:icon_bigg

Pretty great, huh!

could this essentially replace CO2 for a tank? I have a 46 gallon and was planning to use diy co2...but this stuff would be a lot cheaper and less hassle than co2.

Just a little warning guys, Metricide is a toxic chemical. Take care when handling them. Don't breath it, touch it and obviously, don't swallow any.

And chemically it's not exactly the same as excel. Excel is derived from Glutaraldehyde which makes it a bit less toxic to plants and animals.

Metricide is a Gluteraldehyde derivative as well. 2.6% I believe (which is the reason it's "stronger" than Excel) If anything buy this and don't mess with trying to dilute your own Gluteraldehyde. THAT is some nasty stuff lol.

(although mistergreen is right in warning about this stuff as well, it's also fairly hazardous)
