Just for the record I’ve had a few pm’s about which Dino’s I had…. Ummmmmmm idk haha! This was before the microscopes and a Dino guide or really any info on them! It did work on my tank back then and cleared them up rather fast.. before my current tank I had a little cube that I bought used and it broke with Dino’s and the h202 worked but they weren’t leaving any time soon! I believe that tank had procreum or how ever you spell it! I ended up getting my upgrade and just moved all my fish and corals to the new tank with my fingers crossed they wouldn’t transfer and they didn’t! Go figure lol… I didn’t even dip the corals I just pulled them from the dino cube and put in my new 300 without any issues. I left the rock and sand in the cube and drained it
