Thanks John, I think I'd read that thread somewhere in the last few days, but it's a good succinct explanation.

One thing I am curious about with the sulfur system is the whole carbonate reactor part. You generate acidic water in your sulfur reactor, so it's recommended you run it through a carbonate reactor (basically just a bucket of crushed coral) which seems fine and good, because most of us do that for buffering anyway... but wouldn't you be dissolving an abnormally large amount of calcium carbonate this way? The acid gets neutralized, so your pH doesn't go off the charts, but it seems to me your GH would go nuts. This is OK in a reef tank, or a snail tank or something, but I'd wonder about it's effects on the average aquarium.

this explains about the additional chemicals needed with the sulfur

i think this was part of the reason i opted for a carbon feed anoxic filter

Hmmm, well it says it comsumes alkalinity, but not what happens with the byproducts. I guess the calcium and sulfur combine and precipitate out (but where?) and the carbon (ate) gets consumed as bio-sludge, which I guess also could be called a precipitate. I still want to try this... I guess I'll just have to monitor it very closely.

I'm thinking it'd be simpler to build a SLAD reactor that combines the alkalinity source media with the sulfur media... only problem is your crushed coral or crushed oyster shell gets used up faster than your sulfur so you don't just dump more sulfur in when it gets low, you have to remove, wash and repack the whole damn thing every few months. I guess that's better than changing 100gal of water every week.

This is turning out to be a very interesting thread, I'm enjoying the discussion

I'm another newbie doing the research too, so this is perfect! I've been on this trail too. Planning an indoor pond as a retirement project in several years. I'd like it to be for fancy goldfish. Seen the Bakki in action at Keirin Koi in Allentown, PA. Certainly seems very effective--they have their prize koi in the 10 foot deep pool with the B-shower. What about the lack of lighting to the fish? Goldfish decolor without light I understand. How to keep the green water clear enough, but not so clear that they turn white. Any ideas?
