Flourish excel and moss

Hi everyone, so recently i added some moss to my 60cm tank. I am thinking about boosting the moss' and other plants' growth by dosing flourish excel. However, i read in some forums that flourish excel might melt some moss and plants. Anyone here has any experience with dosing flourish excel on tanks with moss? Would it be alright if i use flourish excel in conjunction with regular pressurized CO2? Thank you

If you dose 1x to 2x excel daily, it probably wonít harm moss, but the 5x after WC dosage may.

I once have hard time getting rid of some volunteered moss with no luck until I dosed 5x excel daily for a week, and they are gone without a Trace.

I can't say about any moss aside from Java Moss, but @ 60ml of Metricide daily in my 75g, my moss didn't show any signs of distress.

If your using pressurized the excel isn't going to do much for increased growth. If your using it as an algaecide than it's possible it clean off leaf surfaces that might help it's growth.

I still can't decide if i would give excel a shot or not. Any of you guys experienced significant growth acceleration on moss & carpet plants after you start dosing excel?

Dosage makes a difference in effect.

I don't know what strength your Metricide is. If yours is Metricide 14 which is 2.6% Glutaldehyde, your dosage is very high, more like 15x Excel recommended.

When I dosed 22 ml Metricide 14 (5x Excel or 2 ppm Glut) after WC and 9 ml (2x
Excel or 0.8 ppm Glut) daily in my 75g, my mosses were unharmed.

When I dosed 22 ml daily for a week, my mosses were wiped out. My volunteered mosses look like a mix of Java, Xmas and Fissidens. The reason I dosed 5X daily is to fight Ick which is an ingredient in Seachem Paraguard, and the collateral benefit I got out of it is to help me get rid of the unwanted mosses.

I had an unscheduled fight with some BBA. I slowly raised the dosage by a couple ml every couple of days until the algae died out. I watched all the fish and plants for any signs of distress. I didn't see any problems and all the BBA is now gone. BTW, it was full strength Metricide 14 I was dosing.

Are you sure it is 2.8% Glut as not all Metricide 14 have the same strength.

You are effectively dosing 15x recommended daily dosage of Excel. You have demonstrated that plants and fish have much higher tolerance of Glut, not surprising as Seachem Paraguard instructed dosing of twice as much Glut as yours.

I guess I'll try dosing half of the recommended dosage and slowly go up to the recommended dosage. Thanks for the answers guys

My bottle shows 2.6%. I've been using this bottle off and on for a while. Perhaps it's degraded some. I typically "reset" my dosage any time I start a new bottle. I have already ordered a replacement as this gallon is almost empty. Even if I was still dosing at that level, I would drop it down pretty low and start raising it up again to whatever my current level is, just in case of a "degraded dosage" situation. I keep it in the original bottle, under the tank, in the dark at room temperature but I don't really know how much or if any it is prone to degrade in that situation.
