Battery Gravel Cleaners?

[Le Sorcier]

I have one but its not really strong enough to pick up larger particles.

Anyone got a good one?

i found a marina one on the cheap and place it in the tank when doiing water changes with the feed going back into the tank through the sock thing.
its surprising what it takes out the tank during a change and keeps the tank a bit cleaner but not much
imo there is no real substitute for a good clean

Mine wasn't a good one but it's in a good place..........the bin!
