Glut??

What the heck is the fuzz around that stuff??
Excuse my french ,but how on gods earth can somebody think its a good idea to dump cleaning agent in his tank?? I am new on this board and I am certainly dazzled by all this users who think they do their fish or plants a favor , mixing all that chemical waste to them, if its now fertilizer or pharmaceutical or whatever the market offers...??

Please enlighten me !

A lot depends upon what quantities you use it in, as with most everything.

At 1.8% (18,000 ppm) , glutaraldehyde is a rather potent surgical grade disinfectant, and kills everything it touches.

At >1ppm, it breaks down rather readily into carbon, and doesn't kill much of anything.

Similarly, replacing air with water drowns mammals.
Having small quantities of water evaporated in air aids their breathing.


Of course, there are those who don't like glut, and there are plants that have a hard time with even 1ppm of the stuff (vals, anacharis). However, most plants benefit from it unless there's CO2 injection going on.

And people who use it with CO2 injection use it as an algae inhibitor.

It breaks down into carbon and usually benefits plants. I use Excel in my low techs for this reason. It also kills a lot of algae if you spot-dose it.

To each their own... I'm not going to tell you to use it or not.

I certainly would suggest that CO2 injection is a better carbon source than glut/excel/co2 booster, and I'm fairly sure nobody here would disagree. That said, the growth difference speaks for itself. Assuming no CO2 sinjection most plants grow faster with glut supplementation. It is a simple experiment to run.

I would also suggest glut/excel/co2 booster is substantially less dangerous than most other algaecides, should you actually need to use it for algae suppression. Even hydrogen peroxide, also commonly used to kill algae and fairly safe, is absurdly dangerous in high concentrations (rocket fuel!).

Sometime go look up the ingredients of Algaefix - ie: Ethylene Dichloride a.k.a. 1,2-dichloroethane

If you are interested in some of the science feel free to visit Seachem's site and check out their articles on excel.

Many things have multiple uses at varying doses. Aspirin is great for a headache but taking the whole bottle...well. Thousands of hobbyists use it successfully without problems.

Here are a few links you may find useful.

I find it funny most people would readily dose Excel...however are scared to dose Glut/Metricide when it is exactly the same chemical.

I made the switch a year ago and have noticed no difference between the two...I also tend to mix my Metricide mix a little stronger than typical excel. Most do a 50/50 dilution however I typically use 4.5 oz of Metricide to 3.5oz of water in my 8oz old Excel bottle.

3x75 gallons|2x55 gallons|2x50 gallons|3x40 gallons|1x29 gallon|1x10 gallon

There's nothing wrong with that. I simply thought you were looking for more knowledge on the subject. To each is own.

I like a nice juicy grilled rib eye steak and a beer for dinner. Others find that disgusting. We all have to live our lives for us and not others. The sooner we all realize that and live and let live the better. But that's just me .

You ask rhetorical questions and its annoying to come to the understanding that you are just a dirty hippie with a fish tank and a bad case of Animal rights disorder ... learn some chemistry and piss off .... why don't you just put your fish back in the river and buy a dog? sorry not sorry - but every comment you've posted that I come across is just a waste of time and you seem to "already know the answers" to your dumb questions.
