I have a unique opportunity to become a breeder of live bearer fish for a Local Fish store.It is a good deal for me, the store will provide me with 4x75g tanks each with 3 dividers, air pumps etc.

i know a lot about breeding live bearers so no real questions there, these will not be planted Maybe some hornwart at most.And will rely heavily on Biological filtration.

Which leads me to the questions. I plan to set these up as low cost as possible, and im wondering about bio media, more specifically things not intended as bio media being used as such.


Plastic Scrubbers are they safe for bio filtration(look like the fake loofah only woven tighter)?

The Fake Loofah Sponges that are used to tie riccia to rock are they safe for bio filtration media?
