Ok, so I don't think this is normal at all. My GSP all of sudden stopped extending about 4 days ago. Sometimes the polyps will extend about half the way of what they normally would, but that doesn't last to long, maybe about 10 minutes or so. The above pic is of when i first put the GSP in my tank on June 19th. This is a pic of the GSP on July 12th. My prams are as follows: Ammonia: 0 Nitrite: 0 Nitrate: 0 PH: 8.2 SG: 1.025 Temp: 75 F The only things that I have added to my filters are AquaClear BioMax and Fluval® Clearmax Phosphate Remover. This has been within the last 1.5 weeks. I added the biomax and clearmax to decrease nitrates and phosphates in hopes that the growth of my cayno problem would at least slow down, which it has. I only use RO/DI water for water changes and top offs. I change 3 gallons about once every week. I have a 16 gallon bow front aquarium with around 20 pounds of LR and 20 pounds of LS. All of my equipment is listed in my signature. Any ideas or suggestions are appreciated.
