Darren, I had a fair amount of bubble algae growing in the 170, while running the various reactors I was trying.

Problem is, I feed a ton, so cant contribute it to the reactor alone, I dont think. But I always wondered.

I used only Caribsea ARM. But ran my effluent at 6.5. That kept the calcium at 420ppm and alk at 13dkh.

I swapped the reactor for a large Vario kalk reactor. Its going to be running on my current two tanks. I dont know if it can keep up with the two though. May have to add a reactor also.

As of now I have no algae growing, just a few bubbles left over from before. Will see how this works. I think its more important than we relize, to remove as much of the residual co2 as possible before entering the tank. This would make the use of a second chamber very important.

I dont know how effective it is, dripping it near a skimmer for instance or some other method of blowing it off. For sure, one must make sure the drip is above the water line.
