emperor 400 questions for a beginner
I have the an emperor 400, it so much quieter than the aquaclear 70 I used to run. I am still really new to aquariums and what to do.
The emperor 400 came with two filter cartridges and 2 empty cartridges. I was wondering how often on a 55gallon tank , I should be changing the cartridges. I just completed my cycle and my fish tank actually has a pesky smell to it, so I was thinking of switching the cartridges.
I have also heard people say they add things to the blank cartridges... how do I do that? (Beginner again sorry). Do I need to buy a box of just product and fill it in, or does it need to be marineland products that fit into the empty cartridges?
Any advice and help is greatly appreciated. Thanks!!!
