WOW, so I wanted to shooot you an update. I added an airline from my crawlspace up to my skimmer intake. since doing so I have had very VERY little PH fluctuation. notice the trend starting the 17th.
Fuge is on a reverse light cycle... I have flame algae and Chaeto in there. Got more chaeto last night though so I'll see if it makes a difference.
Nice change Pickupman! I wish I could do that but being on a central wall on second floor the only think I would have access to is the attic, but I don't think drilling into there is all that grand of an idea since I am renting.
yea.. probably not... I was extremely surprised how muchof an instant impact it made. I too have a fuge with a reverse lighting cycle and didnt see much difference.
