In another thread we came to the conclusion that I am still at the tail end of my cycle. My nitrates are in the "okay" range on test strip but no where near the ideal area. Every other aspct of my tank is perfect. No ammonia or nitrites. Perfect salenity, temperature etc. Anyways, my question is what kind of algae is this and can it become a large problem? I also have these little balls of what closely resembles a spiders baby pouch. Are these snail nests?
