Just got turned onto this link: great post with formulas from Scorpio over at AquaPetz, who operates with resulting ppm in the aquarium instead of the % in solution: http://aquapetz.com/viewtopic.php?f=18&t=102

I like this thinking as it brings us to thinking of Glut as yet another supplement (like trace dosing, or macro dosing, or whatever). For example, imagine a calculator that let you dose 1 bottle cap (5mL) into any size aquarium for the target Glut dose. I wonder if folks have accepted Glut to the point this is useful and not confusing, though.

Hii.Turkey has 50% with 2% Glutaraldehyde. Which one should I buy? How should I use? To kill all the algae? Would you help? Thank you.

Hi vuslat,

Welcome to APC! To avoid confusion I would recommend you purchase the 2% solution at first since it is very close to the 1.5% concentration in Seachem Excel.

Normal Dosing:
On initial use or after a major (> 40%) water change, use 4 mL for every 40 L (10 gallons*). Thereafter use 4 mL for every 200 L (50 gallons*) daily or every other day.

For Algacide Properties:
On initial use or after a major (> 40%) water change, use 4 mL for every 40 L (10 gallons*). Thereafter use 8 mL for every 200 L (50 gallons*) daily.

Remember some plants do not respond well to the use of Excel; especially Vallisneria and Ceratophyllum. Please report back with your results!

BTW, my wife and I really enjoyed Turkey when we visited there; especially the wonderful, friendly, people and spectacular history!

Thank you for your interest. Dosing of CO2 do plants in the tank. Tank has got moss species. I use the to kill hair algae. To kill algae? What is the effect to Excel? Greetings from Turkey.

Hi vuslat,

If you decide to use Excel/Glut I would start with the "normal dosing" level. Some moss species do not do well with Excel/glutaraldehyde (just like the Vallisneria and Ceratophyllum). I have lost moss species even when dosing Excel/glut even at the "normal dosing" level.

Have you tried other methods to deal with your hair algae? I find that if I reduce my lighting period, increase my 50% water changes to 2 or 3 times a week, and add a Siamese Algae Eater (Crossocheilus oblongus) I can usually get hair algae under control.

I've tried all the methods. There was hair algae in the Java Moss, Taivan Moss, Sigapore Moss aquarium plants. I did all the solutions, but 3 months is not lost. Not all iron and micro trace element fertilizers. Only used for NPK. The values used are as follows.Excel local practice is dying plants. Try GLUT.Ecxel effective or glutaraldehyde?

My tank measurements:
Nitrate: 10 ppm
Phosphate: 1 ppm
Potassium: 20 ppm
Lighting: 4 * 30 watts Slyvania Aquastar + Grolux
Lighting Time: 8 hours (4 +3 +4)
Tank temperature: 25 C

Hi vuslat,

If you are asking me if Seachem Excel and glutaraldehyde (glut) are basically the same - the answer is yes.

Hair algae in moss is very difficult to eliminate. Sometimes the best thing to do is start new moss clumps using small quantities of your existing moss that you clean well to remove all the hair algae.
