Algae Scrubbers

My tank has recently decided that refugiums are for scrubs. Chaeto, ulva/sea lettuce, Gracilaria, all rejected.

Definitely not a nutrient issue as now that the macro algaes have lost dominance in my system, I'm starting to see a little cyano and HA in both my fuge and display - things I haven't seen in a long time.

I'm toying with the idea of swapping out my refugium for an algae scrubber. Does anyone have any experiences? There's also a handful of 'popular' ones. Turbo scrubbers seem to be the top of the list but after swapping e-mails with him since February begging for a unit, I'm done. Making scrubbers doesn't appear to be a business or even a hobby for the guy at this point. I see different brands like 302Aquatics and Santa Monica and Clear Water. The Santa Monica RAIN2 seems interesting. 

Who uses one? Thoughts? Worth it?

I run a Turbos aquatics on both my systems.  I really like them.  I would say I am still learning the finer points on how to tune them, but my display tank unit generates quite a bit of algae and it definitely keeps nitrates in check.

Argh, Turbos Aquatics. Drives me nuts. Maybe I'll get lucky and find one second hand one of these days.

I'm actually really impressed at the apparent efficiency of a thriving refugium. As soon as I pulled mine, I'm now seeing hundreds of tiny microbubbles all over my live rock which tells me algae and cyano is brewin'. I need to find some alternate means of nutrient reduction until I can get my macros going again. I *really* don't want to bring out the old GFO reactor.

Not surprised at all.  Micheal Palletta back in the mid 90's observed the same thing when looking at Leng Sy's "Ecosystem" method and I've seen the same thing every time I've put macros in a refugium.   My guess is you've been seeing a fairly decent coral growth recently (if you haven't completely stripped out PO4).  Before you go through the work of installing an ATS I'd suggest you read these papers on the competative and antagonistic roles corals and algae have, for both nutrients and microbial processes:

Thanks for the links. I read them.

What was Palletta's observation? Was it lack of coral growth/recession? Or sudden macro algae loss?

Here's what he said ". . . for reasons unclear, the algae has never outgrown the filter and has never had to be removed or harvested, . . ."    Here's the link to Palletta's review of Leng Sy's Ecosystem in 1997 Volume 14 Seascope if you want to read his whole article.  The .pdf has all four issues so you'll need to scroll through them to get to the summer issue it's in.

Here's the best example I have:  Initially Calurpa growth was pretty robust and was a fair amount was harvested from the two ~40 gallon refugiums 3 or 4 times the first two years.  It was harvested only one more time after that and the last two years even though there was a fair amount that showed some growth with new runners overall there wasn't any significant changes in volume and none was harvested.

 

And here's a video of the system.
