Hi guys,
Have a 7' * 2' * 2' tank ordered and thinking of using no substrate so it's easy and quick to vacuum up the fish waste.
Is this a bad idea though because i'll only have beneficial bacteria in the filter?
Is there usually a lot of bb in the substrate?
Going to be using a FX5 and will have big messy fish in there - arowana, oscar etc.
Thanks for the help
Alan
