Firstly to all FX5 users, this is a little trick i picked up a couple years ago... Budget foam from Maidenhead Aquatics, I buy "Set 3", £11.99
You get a nice big sheet of coarse, medium and 2 x fine (different sizes and combos available)
After cutting them up soz didnt take pics during, you get 3 x rechanges for your filter thats easy a years worth, £1 a month haha
Got a good deal on lava rock today so stocked up, may have baught to much, but in malawis theres never too many caves, will aquascape later but just dumped in looks pretty cool as it is
£30 for the additions of rocks (thats almost all of it lol)
Have taken the old arcadia apart and pulled out its guts, will fit it into a lid tomorrow
