laguna sub filter. anybody have any comments about em?
worth buying? [online $50ish/ petstore $70ish] or is there an easy DIY underwater filter i can build?
i've got the chemical and bio filtration down [i've got bacteria for ponds and carbon/ammo in my filter pump cage] but my pond is in dire need of some mechanical. there's stuff floating around everywhere and its probably making conditions really bad.
thanks
