I bought a battery powered gravel cleaner off Ebay but when it came it had no suction and was useless. (got refund) So which gravel cleaner do you have and is it good? I have to do a full tank clean about once every 2-3 months (water changes in between) more often in summer and its so annoying so think a gravel cleaner is the way to go. I'm off to pets at home tomorrow so if theres a decent one in there i'll get it or off the internet will be fine :)
TIA
