Right guys, i'm changing my internal Fluval U3 to external Fluval 305 today on my 125litre tank. Wish me good luck as this is my first time with anything fish related
Currently i'm planning to put the following media into the 305:
Bottom - Sponge from Fluval U3
Medium - New Bio (305) + Fluval U3 Biomedia (cycled media) *fingers crossed*
Top - New Bio (305) + polishing pad (probably)
Advice on anything much appreciated.
sounds good, fingers crossed for good seeding.
