I'm getting a 250L (55gal ?) aquarium. I was wondering if it's ok to use Fluvial 2+
internal (my old one) and a Fluvial 4+,which I want to buy?
thanks.
it all depends on stocking levels in the tank. if its only ligfhtly stocked then i would say it will be fine, if you want to fully stock it with messy fish then ide say you be better off putting the money from the fluval 4 towards a decent external filter.
but in anycase if you can afford to get an external then ide do so anyway, that way you never haqve to worrie about upgradeing filtration in the future.
