oddly enough thats a trend im starting to notice with marineland, there products seem quality and work very good for a while, then some thing goes wrong. i noticed the sound problems one my penguin after a few months, the petco brand filter is whisper quite in comparision lol.
but i guess thats a trend now for products, my dad complain of the same things with his power tools, he buys a new set every 5 or 10 years, the ones from over 30 years ago still work while the newer ones break or decline in performance after 5 years.
