Hey im about to switch from a Tidal 55 HOB
to a fluval 307 ive currently got matrix in the HOB
a bit more than was supplied, firstly what is the best way about going through the switch. Should i just take the media from my HOB
and add it to the 307 or should i run them both for a period of time and if so how long?
I will be approx tripling my media capacity i have a little bit of fresh matrix left over ill also have the fluval biomax the filter comes with and i also have some spare aqua one rings. What would people recommend using or should i purchase some more media.
