Default glutaraldehyde instead of excel

Hey guys

Last week I have been using glutaraldehde in place of excel.I'm using a 2.8% solution.It's suppose to be about the same as excel but alot cheaper.I paid $16.95 a gallon.

I tried it in two tanks,a 10 gal. planted and a 60gal. planted.
It had a different effect in each tank on some of the same plants.Below I'll list each tank with the dose and effect I noticed.


60gal.,192 watts,11hours lights on,co2 injected,ferts daily,plants are red tiger lotus,rotalia indica,sword,ludwigia,anubias,hair grass and crypts,34 fish.

I dosed 30ml 9/23/6 after a water change then 10ml daily.
On 9/25/6 the angelfish spawned so it seems to have no effect on the fish.
9/27/6 the sword plant started growing fast.3-4" growth of new leaves daily.this plant has not grown much in the last 3 weeks.

It's been a week so far,water is clear,plants are growing fast and the little bit of algae I had is gone.

riccia is ok.

Now for the 10gal.,30 watts 8-10 hours,no co2,ferts daily,plants are sword,red tiger lotus,ludwigia,and bolbitis,tiger barb fry,cherry shrimp and alot of hair algae.

I dosed this tank heavier to see what would happen.
5ml daily.
9/23/6 dosed at 10:00am and by 7:00pm algae shows signs of dying.fish and shrimp are fine.

9/24/6 riccia is dying off.All the algae dead.fish are fine.water is a little cloudy.

9/25/6 water is clear.I have a few strands of moss in this tank.I think it's java moss.It is growing very fast.

9/30/6 moss has grown around 10" this week.this moss has been in here for 8 months without much growth.The bolbitis is a little darker green and the leaves have widened.Looks healthier then it ever has.

Other than the riccia dying and the water turning cloudy one day it seems to work well.

If I notice anything else I'll add it to this post.
