Hi everyone
I've got a question about filter media for filter cups.
My tank is designed in such a way that if I don't use the filter cups/sock chambers it makes a lot more noise. Because of this, I'm forced to use them but haven't used cups in the past.
I've got a 2kg bag of sea shells I bought online and was wondering if I could crush some of them up to put in the cups?
Any thoughts on the pros and cons of this?
The shells are a mixed bag if that helps.
Thanks
Stef
