Liquid co2

[Aquaticfan]

Seachem flourish is a watered down version of glutaraldehyde. This is a quote from Wikipedia's site on this stuff.

"Glutaraldehyde is an organic compound with the formula CH2(CH2CHO)2. A pungent colorless oily liquid, glutaraldehyde is used to disinfect medical and dental equipment. It is also used for industrial water treatment and as a preservative."

If I were you I wouldn't put that in my tank even in the smallest doses.

If used in correct doses its harmless to your fish. It can be dosed in higher amounts. I actually buy gallon bottles of glutaraldehyde and dilute it with distilled water. My use is for specific items though to control any small algae issues not so much as a carbon suppliment as I run co2.

If you use it with shrimps it can kill them. It must be deluted further and dosed smaller doses.

It is consumed rather quickly in the system.

Excel has a algaecide in it which is why it will kill algae. It is best used in a syringe and shot right at the algae. Because of this algaecide, it will kill more simple plants like Vallisneria. Excel works well in small tanks. But if you plan on keeping the tank long term, then pressurized CO2 system will pay for itself eventually. Plus pressurized CO2 is just easier. Put everything on a timer, and you're good to go. Algae is a problem when you have too much of something. Too many ferts, or too much light. Figuring out what the problem is and fixing it is a much better solution that constantly adding something to take care of it. And Excel will kill inverts.

Well, lol some Other areas we don't agree.

Excel has no algaecide in it. You can call and even ask seachem. Its their branding of glutaraldehyde. I buy glutaraldehyde sold as metricide 14 and mix it down with distilled water. Its cheaper and lasts much longer the excel. The biocidal effect of glutaraldehyde kills most algae at concentrations of 0.5 - 5.0*ppm. These levels are not harmful to most aquatic fauna and flora. There have been some though at those levels have issues with super sensitive plants and mosses. And some inverts. I've got tanks with shrimps that I run lower dose amounts and never any issues.

I partially agree with you about causes for algae. It is a balance issue. But it has been oroven that the biggest factor is light intensity and or duration. Nutrients or ferts is not so much the case. If overdosing those were an issue then fert dosing regimes like EI- estimative index dosing created by plant pros like tom barr wouldnt work and wouldn't be one of the most used in the hobby.

I've personally run amounts exceeding 2 to 3 times what's needed for tests anf never any issues.

Algae also does very well where plants struggle. When plants thrive algae normally does not.

I have contacted Seachem about the algaecide, and yes, Excel does have it. I would not say it does if it doesn't.
And I have no idea who you even are lol.

 

[sexyandiknowit]

Sensitive rotala,ludwigia, and pogostemon species hate this stuff. Not all plants do well with it.

H2o2 is cheaper and safer for eliminating nuisance algae.

Furthermore the money spent on metricide/excel in an 18 month period will pay for a CO2 setup in most cases

Sorry but I have to call you out on this one.. Excel DOES NOT contain any algaecides.

Look right here on their product data on their web page. It says nothing about algaecides.
Product data sheet.
http://www.seachem.com/Products/product_pages/FlourishExcel.html


Here is a quote directly from their web page on their Q and A section for Excel. Its the 4th Q and A down.

It reads
Q: I read in a plant book by Pablo Tepoot about a product by you called Health Guard. Is it safe to use with Plants & fish to control algae. Could you help me in find somthing that works.

A: There is a comparable product to Health Guard in our freshwater planted line called Flourish Excel. Like Health Guard, this product is not sold as an algaecide.

It states their in their word that the product is not sold as an algaecide. Thus not having any algaecide in it.

Here is the MSDS info.
http://www.seachem.com/support/MSDS/FlourishExcel.doc.pdf

On the MSDS info the product listed as Components (Chemical Identity; Common Names(s)) are....
2% Aqueous solution of the acetal form of 1,5 pentanedial, CAS 111-30-8


This compound listed if you search it pulls up exactly data for that.

acetal form of 1,5 pentanedial, CAS 111-30-8 Is the identification number/Name for Glutaraldehyde. According to the MSDS sheet of Excel it has a 2% solution of it and only it in its contents.

Here is the info data sheet on Glutaraldehyde. Good read and gives you some info on it.
http://www.nicnas.gov.au/publications/car/pec/pec3/pec_3_full_report_pdf.pdf

If yoused in correct doses it can be an asset and I recommend it. Like I mention before I actually buy a more concentrated Glutaraldehyde in a gallon and I dillute it to the correct ration using the WETS calculator for Glutaraldehyde.

We dissagree about how often you clean canister filters and I just got out of the hospital.. Maybe that jogs your memory??

I never had any issues with any of my Rotala, Ludwigia or Pogostemon plants. The only stuff ive seen real issues with it are Crypts, Vallisneria, mosses, Anacharis, moneywort, Riccia..........
BUT This also depends on how much your dosing. Excel/Glut. in high amount doses can kill all plants. Correctly dosed you shouldnt have issues.

I do agree with you that Co2 injection is a better way. I use Co2 injection on my tanks along with EI dosing. I also on occasion dose Glutaraldehyde to help boost and keep algae concerns to a minimum. As my tank grows in and that takes all of 3 to 4 days The Co2 circulation becomes a little less. Adding the small doses of Glutaraldehyde keeps any potential algae at bay and boost the plants even more.

For cost btw when I buy Metricide 14. 1 gallon cost me $25.00. It gets dilluted down with distilled water to a correct ration. When its all said and done I have 1.7 gallons roughly. Thats enough to last me a year for $25.00. Thats way cheaper then Excel. Or even Co2. I go through a 20lb CO2 tank in about 5 months.


I think any tool that can help benifit an aquarist in their planted tank should be used if they can. Its always up to the user if they feel they want to do so.

Yes it does contain an algaecide. For legal reasons, they cannot say that it does. All that info you linked doesn't say that though. Who do you know who works at Seachem? Do you get all your info from a web site? Do you believe everything you read on the web? You're not calling me on anything.

Good luck to the OP.

Not being sold as an algaecide, and not having a algaecide in it are 2 completely different things.

You changed your avatar. That's why I didn't recognize you. Hope all is well with you .

I would hope that a reputable company such as seachm would be putting correct and accurate information on their website about their products. So yes I do happen to believe what they have on their website.

What legal reasons would they have to not list or tell you it does or doesn't have an algaecide in their product? Actually legally speaking they could have bigger issues by not telling you it has some form of algaecide.

I have talked with product designer/engineer at their company. While they claim its a special formula of glutaladrehyde they also say it has no algaecide. The effects of the glutaladrehyde are in fact what kills algae itself.

Btw if you read all the links I posted then you would have seen a msds sheet link for seachem flourish excel. An msds is a legal document regulated by osha, DOT, NFPA and the government. It has to 100% contain all chemicals, items and ingredients as well as potential hazards. The only ingredient listed in excel was the chemical components of glutaladrehyde. See the link after the msds link and in the section of identification and it list exactly for verbatim what's on the excel msds as the only listed compound. Nothing else nothing more and nothing less. Legally they would have anything else in there if it was. So no algaecide is in it.

If you like I'd be glad to email the tech dept at seachem to have them answer directly just so we can clarify and get the facts directly from them and eliminate and confusion or misinformation so we all know?
