Hi Phoenix! I see you're a rather active member on this forum! (how have you found the time to post 9,565 posts! )
Thanks for the advice. I didn't mean to suggest that I had the brown algae issue - it's a new tank and no algae yet, but I'm going to do whatever it takes not to get it. (I battled with it in my previous tank which had an undergravel filter and reoccuring high nitrate/phosphate levels which I think triggered the algae problems)
So really my current issue is how best to mechanically remove the clouding (which I'm figuring must be caused by disturbed Aquabasis) from the water. I'll give carbon a go just for period to see if it helps remove the initial clouding. (along with water changes) I don't see myself using carbon long term.
Thanks again,
Brendan
