Hi,
I've got a Fluval Duo Deep 600 set-up (84 litre tank) which came with a Fluval 2 Plus Internal filter. I'm thinking of changing to an external filter, but as I'm quite new to all this, I'm not sure if it is worth the extra cost.
The existing filter works ok, but the water never seems to be crystal clear and there is always loads of mess at the bottom of the tank even though I do a 20% water change and gravel clean every 10 days. Would an external filter improve this and if so any recommendations? Also, can I run an internal and external filter together, or would that upset the fish...?
I've currently got 5 adult fish (2 mollies, 3 platies) and about 15 molly babies which are about 2.5 months old.
Any suggestions / thoughts gratefully accepted! Cheers.
