Any way I have bought the Oase bio thermo filter I wished I hadn't seen the video, pimp my filter when he describes the filter having a terrible flow system and ends up cutting slips and drilling holes in the filter casing, but anyway I've bought it now.
My questions are, it comes with two departments containing sponges would it be okay to remove one of the sponges, as in my 125 tank I have a bag of ceramics that's been there for 3 months and put them in the new filter tray, and leave them in permanent,
If I did this, would it still be beneficial to use Goop, if not, would this speed up my cycling, and using this method with testing would I have to feed ammonia each day or weekly, and if yes roughly how many drops for 70 litre tank.
