well three updates tonight.
after emptying out another two litres of cloudy water from the waste collector, which by the way is the greatest invention ever (i'll elaborate on the skimmer thread) i tweaked it this morning and instantly i had a massive head of foam form, not just lots of bubbles but real foam. :bounce:
second: i did some tests
Nitrate: 0
Calcium: 400
kH: 8 (bit low but acceptable)
third thing is a little weird, i took some xenia out to rossco's house (probaly about 70% of the total xenia in the tank)
as soon as i took it out i noticed some of the white xenia wilted abit, by the end of the day it had almost shrunk into non existance and then by the end of the next day it had gone. :-?
