hi i have a 135 gallon tank. it is 6 ft. by 18 in. right now i have a gravel cleaner but the cleaning tube diameter is only about 1.5 inches. and it takes forever for me to clean. i have been searching around the internet and the biggest i could find was 2.5 in. i want to know how you guys with big tanks clean your gravel faster. are there any really large gravel cleaners with a wider cleaning tube that i am missing out on? i need a tube thats wider so i can cover more ground.
thanks
thanks
