Fissedens and Excel - Plant Physiology & Emersed Culture

Jeff.:P:. · 07-16-2008, 10:21 AM

Well last night I took a rock that had some Fissedens Fontanus and drop into a bowl with a 1/10 solution of excel and water. In order to kill off some string algae that started on a corner of the rock. For those of you that don't know Fissedens, Moss's, and liverworts do not do well with direct Excel dipping.

100% hindsight

I thought a 1/10 solution would be diluted enough, well I was wrong. Today the Fissedens looks faded green and I expect it only to get worse. I doubt it will make a recovery. I hope that the Fissedens won't leach any of the excel to the rest of the tank and affect any of my other moss's ( I did rinse the rock off with clean water after the treatment.)
I might be in the market for more Fissedens Fontanus soon.

Live and learn.

Mod's; Sorry if I placed this in the wrong Forum, please move to General Aquarium Plant Discussion Section. I think I'm still sleeping. :P

I had the same problem I had string algae and I did spot dosing with a turkey baster and the next couple days it turned gray and it didnt kill any of the algae. I dont think it will leach anything and it might have a chance to come back.

Did your's recover after turning gray? And how long did it take to come back..

No it didnt but I did multiple spot dosing and I just got some more and took the old stuff off. When I initially got it it was in bad condition and had brown spots on it. I got some more from Tex Gal and it is now growing great. It is worth a try to put it back in tho.

That stinks

How will you get the algae off now? Or is the algae dead?

Jeff.:P:. · 07-18-2008, 10:54 AM

The algae did die same as did the Fissedens, I changed my lighting period to a mid day burst, more water changes and lighter fert. schedule. Seems to be working. Luckily I had some more fissedens to spread around. So it's all good.

Just a heads up; fissedens, liverworts, moss's, mini-pellia do not like Excel in any concentration.

It a good thing I read this. I was about to do an excel tank treatment to get rid of what looks like clado and bba. The tank has lots of fissidens and I definitely do not want to have to pull the driftwood out or buy more.

Sweet, I'm glad it saved some one.

Does normal dosing with Excel kill mosses or does it only happen with OD'ing?

I was dosing my tank at one point normally with Excell, the coral pellia (liverwort) turned translucent and died. Some of the hardier moss's (java,ect..) I'm sure will do "ok" but I'm really not sure, and I wouldn't want to try it. Fisseden's had slowing growth and turned white.
