Sam,
P. helferi is not one of the things that Excel kills.
This is P. helferi grown with a every-other-daily 2X overdose of Excel at an average water temperature of 30C.
Excel, dosed per bottle does not kill many things except for algae, liverworts and bladderworts, which are susceptible. There have been some reports that Excel doesn't agree with Vals, and as SunnyP advises, E. densa, however, these are exceptions to the rules. Most things in the tank respond positively to Excel.
Neither Excel nor temperature is generally responsible for melting plants.
Tissue loss of S.A.M's , including holes, browning, softness, blackening, translucency, black spots and disintegration is a direct result of poor CO2 and/or poor flow. Proper adjustment of CO2 distribution will cause these faults to recede. Plant structure is primarily composed of carbon. You would be hard pressed to find a single molecule in a plant that does not contain at least one carbon atom. Planet Earth is a giant carbon based organism. Therefore, loss of structure can only be attributed to loss of carbon.
Cheers,
