I've been overdosing with excel to help get rid of my algae problem. Now my vals are starting to melt.I stopped dosing and pulled most of the dead leaves out. I tested ammonia and it's @ .25ppm. I did a 25% water change. Nitrates and nitrites are 0ppm. The test kit is kinda vague the aquarium pharm test kit reads .25ppm and the Tetra one reads 0ppm. Do you think I should pull all the vals out? or any suggestions on what to do besides doing water changes?:icon_ques

Excel will melt riccia, vals, fissidens...and probably some other stuff I can't remember....not always, but these species are especially sensitive to it.

Oh! Anacharis too.

Do you guys think I should pull the rest out? Will it keep dying? or will it bounce back?

your water params look suspicious..
in an established tank... ammonia, nitrite should be 0ppm.. while nitrate can range 5-20ppm

it's not the cause of your melting plant but is probably the reason for your algae.

Excel is only available in the tank for 24hrs before it is biologically consumed. If You are going to quit dosing excel then I would leave the plants in--the damage is done. If you are going to keep overdosing excel--then I would remove them.

Add anacharis to the melting plants above....

Im new to this and probably the last to be giving advice, but I think I just turned the corner on this same problem. My brand-new vals were taking off like crazy but I then had a huge beard algae outbreak and then the vals shut down and turned brown. I did a WC and started a 3x dosing Excel regiment to kill the algae on 4/1. I chopped the Vals down to near stumps because they were saturated with algae and ugly.

During the Excel treatment, I tested my nitrates and they were zero also... which I tought was good until I read enough Tom Barr posts. I ran to Home Depot and bought Grants Stump Remover ( KN03 ) and dosed my nitrates up to 20ppm with 2 teaspoons 4 days ago. I have already noticed my vals are starting to sprout back nice green shoots, and the runners are coming back to life, which they have not done in about 3 weeks. Spot treatmets burned up whatever leaves I treated, but it took the algae with it. The overdosing is not affecting my riccia at all. My anacharis is deep green and growing about a 1/4 to 1/2 inch a day ... maybe my plants are all mutants.

I believe once I got the nitrates in order the vals improved but I'll have to check back in a few more weeks. :) I used the API kit from Petsmart and also the little 6-test plastic strips, they appear to have consistent 20ppm results on the nitrate test that the dosing predicted I should have.

I have a 110g tank and putting in 35 ml Excel a day.... Florish and K 2x a week. Probably will stop over-dosing this weekend since all the algae is white and dead:thumbsup: and I'm going through almost a bottle a week.

I'm very interested my situation is similar to yours... good luck.
