Yes, it's definitely less than yesterday, it just that yesterday it wasn't quite a 3. I just added another 1 cc and that brought it to a solid 3. We'll see what's happening tommorrow. I don't have a test for nitrates yet, but the reason I mentioned the algae growth before is that I thought it couldn't occur
without nitrates...
Unfortunately, I have been peicing what I have so far over the last several months, and I have to budget for everything (including a test for nitrates

) so I can't get everything at once. What do you recommend, however? I'm curious...
