i dont use an ugf at present but i am buying a larger tank (180 ltrs) nxt month. i shall be using an external filter. my questions are:
1, are ugf,s any good?
2, should i use one with an external filter?
3, could i connect it to the ext filt or would i need an extra filter?
4' i use a syphon gravel cleaner, could/should i still use this with an ugf?
many thanks in advance.
