Bill - While I have added some SMB breeding areas, there will not be much rock cover compared to the pond size (way too muck hauling of rocks). I will be adding lots of emergent plants and water lilies which I hope will provide cover. I do not yet know how many submerged plants will grow. I plan to definitely add FHM this spring, but am still unsure of GSH because I am concerned that they will interfere with SMB recruitment, but I am leaning toward it since I will not be feeding. Based on your recommendations, would there be any advantage in adding the FHM this spring, the GSH next spring, and the SMB the following spring, or is it just as good to add both FHM and GSH this spring.
