Dry start seems to be the way to go with the mats. I purchased a bunch of HC mats a while back, they came on coconut fiber that turned out was infested with all kinds of algae. The HC looked awesome and was very healthy, I peeled it off as you did. They seem to all be grown immersed from every supplier. I didn't dry start so while the plant transitioned to submerged I faced a lot of algae coming up from the roots attacking any melt. It bounced back in the end but was a PITA to keep the hair algae from taking over during this transitional period. If I ever plant HC again in tanks down the road I will dry start no matter what.
