I had been neglecting my tank a bit as of late so I'm rejuvenating it by giving it a complete makeover, changing substrate, new hardscaping etc. I'm also switching filters as I don't like the space my internal filter takes up and I want to go for an iwagumi style set-up.
Anyway, my question is, how do I try and transition between filters. can I try and fit my sponge from my internal filter into my external (fluval 107) or will I run both concurrently until the external has enough of a bio load? Or should I re home my neons and start the cycle process again?
