Aquarium Advice Addict
I'm not super into my penguin 350, I haven't had issues with the bio wheels spinning but I find it gimmicky and unnecessary. I have 2 marinelands and dislike them, I have 5 various sized fluval aquaclears that I absolutely love. I can't find a single fault with any one of my fluval filters. They are top notch, from adjustable flow rate to media customization, to functionality, they are hands down superior.
