Aquarium Advice Regular
I thought I read somewhere (maybe in this forum, but I can't find it) that an undergravel mechanical filter is not good with crayfish since they dig. I am upgrading from a 20g to a 55g used tank, and the underground filters came with the tank, so I'm not sure what to do with them. I just bought a filstar xp3 for my 55g, but if it would be helpful and benefictial to run the underground filter as well, I'll do it.
I don't quite understand how they work since it just seems they suck up the water and waste that falls down to the bottom then just spits it back out to the top. I know this increases circulation through the gravel, but it sill doesn't completely make sense to me since its not trapping waste at all, or really filtering it at all. I suppose the gravel is the filter? Or maybe I am missing some parts.
I suppose I could use airstones to power them - one on each side. I really don't like my aquariums to make too much noise, and the airstones I have make a bunch of noise. I am also concerned that having two uptake tubes spewing out on both sides in addition to running my xp3 will make it look and sound like I am trying to start a wave pool!
Anyway, please give me your thoughs.
Thanks.
