lol that guy assumes everyones an idiot...
i actually don't concider green algae a type of "filth". filth is more to do with ammonia/nitrite and poop. like in finding nemo, that was totally BS. typical movie. that is not what a dirty tank looks like, maybe one with an seriously BAD algae bloom.
also this hose wont work with a sand bottom like i have. and this video proves her tank is REALLY under filtered!! whats she got on there? looks like a 20 gal with like a 5gal filter...
ALSO, theres a second vid in that videos "other videos" section labeled "cool new way to clean fish tank" its all blue gravel and the guy is an IDIOT. he says "this is how you clean all the poop and never loose any water!" HELLO!! Water changes???
idno i just get really ticked, whats worse than a junk fish keeper who doesn't know how it should be done is one that doesn't know how its done AND teaches their ways!
