well you learn something new everyday!
i could do with some advice on my new tank if possible,
800 litre tank with fx5 running for 3 days now with a few small fish added on day 2, i also have a fluval 405 running for 2 months in a 180litre tank with my quetzals. i want to move the quetzals in asap!!!
would moving the 405 over with the fish enable me to do this???
thanks
