Thanks very much for chiming in, Doompie. Even if it's secondhand and anecdotal, it's good to have confirmation that there's more to this than a crackpot hobbyist coming out of nowhere with a plan to...

The name of the game is bioremediation. If you're satisfied controlling P through chemical means, I'm not going to tell you you're wrong, but please understand that from my perspective, that method...

If you find the information useful or the Standard Model plausible, please direct the attention of others to it. I don't get out much.




I like the cut of your jib, Garf.

Cyano wants to...

In the interest of full disclosure, I'm Totoro. The Pacific NW Marine Aquarium Society is the local SW fish club, and they're kind enough to tolerate my little lectures as I think through this stuff....

If you've been puzzling over cyano's relationship to P accumulation in the substrate, Garf, you may find this interesting. Be sure to mouse around over the text -- there are several links in there,...

First off, SM, I must respectfully note that you're declining to address my actual thesis, which is that green algae with an N:P ratio higher than the N:P of the food going into an aquarium cannot...

This is old hat. It predates the interwebs, so it turns up in textbooks and is pretty much taken for granted -- like the ocean's food web being dominated by bacteria, not algae.

The 10:1 and 20:1...

Hi, everyone. Long time no see.

I've had phosphorous on my mind for a while, now, and I've come up with a notion or two that might be of interest in these parts. As before, apologies if what I'm...

Back In The Day, these were called "plant filters", and the old timers got the idea from professional fishkeepers at the big, public aquariums. Peace lilies and pothos were (and perhaps still are)...

Could be worth your time to read through this thread over at The Planted Tank Forum. As others observed, this may be cyano.

From looking at the PDF from Branch Environmental that you linked to, I'd venture to guess that in an aquarium setting, their air stripper design (page 5 of the PDF) facilitates aeration and gas...

Your point about java moss is a good one.

I have a shrimp colony living in an unfiltered 10G tank with a shallow sand bed -- there's an airstone in there for circulation, but that's it -- that's...

That's the beauty of algae scrubbers: instead of trying to replace or supersede existing natural processes, scrubbers put these processes to work on our behalf. If I'm correct, then they do this even...

We must guard against the acquisition of unwarranted influence, whether sought or unsought, by the Aquarium-Industrial Complex. ;)




Interesting link, but I'm analog... Anybody know what the...

Hi, SM. Thanks for chiming in. Nice to know my mental model of what's going on jibes with yours.

I guess the take-home point here is that if indifferent maintenance or some sort of scrubber mishap...

How Scrubbers Improve Water Clarity, or The Microbial Loop: Our Invisible Friend


This came to me after reading Wetzel's "Limnology: Lake and River Ecosystems", which freshwater types may know of...
