I've been fighting what looks like a type of dino for the past 6-8 months without much success. Every time I try and siphon it out or clean it off the rock or sandbed, it seems like it only comes back stronger. Tank is almost 2 years old at this point, with a decent sized cleanup crew. Please let me know if there is any other information I can provide to help identify and confirm what is going on. Thanks.
