This is a question for those who have the Oceanic slimline 2. I just got a brand new one and I was surprised at the purge cover material. It's very HARD to press on it to get a full purge! The cover is not the 'soft' type like a normal octo. It is so hard that I thought it was designed to prevent free flow or something. If you have an Oceanic slimline 2, is this the same for you? Or i got a defective one? The cover looks fine to me except the hardness. I hooked it up to the tank and it breathed ok, not the smoothest, but ok. Thanks.
