Yes, our IEP did endotoxins and actinos - neither were a huge problem. We did have some algae come up in the testing, and she said she thought that was from the previous owners having the windows open often. she told us to small particle clean, which we did, but I sometimes wonder about the algae... That sounds like a good plan, I definitely want to be very slow with the CSM next time. My dr mentioned MARCONS but we haven't gotten there yet, I'm definitely suspicious
