Damn!

I think they adjusted the shipping charges because I cant get it at that price anymore.

Do you guys have any other reliable sources?

Hi!

I was reminded you folks paved the way for this. Here's a calculator you may like: http://glut.petalphile.com/

(Converts Cidex Plus, Metricide 14, and various Glut concentrations to 1.6% Glut solutions. Needs Javascript and a modern browser to work properly.)

Thanks!

Hi wet,

It looks like you have made a good start on it but it has two issues.

First why are we using 1.6% instead of the Seachem Excel concentration of 1.5% as the target concentration? The resulting concentration is about 7% stronger than Excel and requires 7% more Glut/Metricide/etc to formulate.

The second issue is a "bug". If I indicate I are using 5% Glut as your source solution the result indicates I am using a 10% source solution and indicates an incorrect amount (by 50%) to add.
Bug


Here are some screen shots of the Glut calculator verses wet's calculator for the same volume and concentrations. Disregard the cost/ml and Total columns, they do not apply to this calculation.

I'll stick with the Excel based Glut calculator on my computer at this point; but this is a good start for an online version.

Thanks,
-Roy

Hey Seattle_Aquarist. Just syncing up these threads. I picked 1.6% because I'm not entirely convinced Excel is exactly 1.5% Glut until someone pulls out a spectrometer (and the difference between 1.5% and 1.6% is not significant), the Indian poster we cite as a chemist and attribute 1.5% to has some non-chemist-like posts in the rest of his history (not that I'm a chemist), and Azoo's and EasyLife's recommended dosing are in the same ballpark

But this is the second request since last night to move to 1.5%. So you've got it.

Thanks for catching the 5% bug!

Also added Metricide 28 on Joraan's request.

Have fun!

Hi wet,

It is an excellent first effort, and for those that don't have the ability or inclination to use an Excel based calculator it will be an excellent asset.

Keep up the good work!

Thanks,
-Roy

Forgive the cross post, but here's an attempt at a quicker and simpler tool.

Just wanted to report back after 41/2 months no problems noted by using the activator that accompanied the Metricide. However next time I will not uslast time it. I had purchased the metricide 28. I see Tex gal picked up the 14%. Is one better than the other>

BTW between EI, good "stuff*and metricide......my plants look great

Hi Aquaticz,

I'm always glad to hear that things are improving and / or going well for another. I found there are no "miracle cures" for algae, however that addition of Excel or Glut is definitely part of my overall nutrient and maintenance program.

When I start to see algae becoming an issue in my tanks it is typically a result of light (too much), nutrients (to much or lack thereof), and not doing adequate water changes. If I am reasonably conscientious about my maintenance I am usually rewarded.

Glad to hear things are going well for you.
