To Fuge or not to Fuge...that is my question?

[reefgeezer]

No. With a clean tank, adequate flow, and alk, the PH is not a problem.

+1... I think the acids produced by the decay that occurs in the fuge is responsible at least in some part for lower pH. I'd imagine there is a little drop at night in my "fugeless" system, but if the pH isn't depressed to begin with, that little drop doesn't matter. I suppose one day, I'll fire up the old Pin Point and find out the exact numbers, but truthfully, it's been a long time since I worried about it.

I had a fuge but do not currently and I miss it. Great place for pods to reproduce and helps balance PH when run on a reverse light cycle. I am looking to incorporate a 20 gallon fuge into my upcoming build.

I'm sold on my fuge. I keep both chaeto and caluerpa on a reverse light cycle. My pH is generally stable at 8 during the night, then 8.2 during the day. After I harvest the fuge to next to nothing, my pH drops to 7.8 at night, then 8.1 (maybe) during the day. As soon as the algae grows back to before I harvested, the tank returns to a pH range of 8-8.2.

I use Kalkwasser to stabilize pH, but I did enjoy my fuge on my nano, for the pods. Mine was about 3 gallons, while my display was 15g. It's the only tank I've used one on. I probably won't use one again.

I've run my 10 gallon with AC70 mod fuge stuffed full of cheato. I have it lit 24hrs a day with a 10w cfl, mostly because I don't have room left on my power strip for a timer. I use it for nutrient absorption and pod growth. I don't use a skimmer and I've never had detectable nitrates (doing 10-15% water change weekly) in the past 2 years keeping Sps.
