Hi ShaneSmith,

I have tanks with both high and low bioloads. In my 45 gallon I have a very light bioload (10 Corys, 3 Otos, 1 SAE), a little GSA, and that's about it. In my 30 gallon, I have a very heavy bioload (2 full grown Silver Veil Angels; 15 Cardinals, 8 Rasboras, 6 Corys, 3 Otos, and 1 SAE) and no algae!

Both tanks have medium to low circulation; about 2 WPG; CO2; dose PPS-Pro; use Glutaraldehyde at 2X rate; and have a 6-8 hour photoperiod split 50/50 morning and evening.

If you need more info, let me know!

Hi ShaneSmith,

Yes, I use Glutaraldehyde mostly for the algae control, secondarily for extra carbon for plant growth. I first started using Flourish Excel for algae control after reading this thread:
http://www.aquaticplantcentral.com/forumapc/algae/3806-flourish-excel-got-rid-all-my.html

It worked miracles in my tanks, but even buying the 2 liter bottles online, Excel was expensive. Then I found this thread lurking in an APC club forum talking about Glut being the active ingredient in Excel. http://www.aquaticplantcentral.com/forumapc/south-western-ohio-aquatic-plant-enthusiasts/31615-glutaraldehyde-instead-excel.html
I bought glut online and have been using it for several months with no noticeable difference compared to Excel.

Several other members of GSAS are also using Glut. There are posts from me in both threads, one post includes the concentration of Glut in Excel. Hope this helps.
