Crash, I seem to remember that you have a large bag of carbon in your sump, do you remember if you did this with the "other" green screen or was the carbon put in at a later date.
U dont miss a trick i always run carbon with the scrubber as im a firm believer that doc's get to high and cause problems i have dealt with it myself before.
Happy new year crash. Our American friends have got a while to wait. If they beat that firework display, I'll eat my hay.
Digging through my hard drive and found pics of your scrubber growth after you got it Day 10 (from scratch) Day 11
