Ok, I have had an influx of algae lately and it is driving me crazy. I don't think it is having an effect on my plants, but it is unsightly to say the least. What causes this? I just switched to using a canadian peat, and that seems to be the source (I switched from scott's), but it seems that the stuff I have mixed up with the scott's is also allowing it to grow. I usually just put some peat on top, or "till" the top of the soil with a toothpick, and that seems to work. I am worried about my seed, sars, and drosera. I did have problem with the gemmae I received, in that I only got one to take and algae, was rampant. any help would be appreciated. I do have ban rot and another type of fungicied from flytrap.com.
