AHH now that I’ve got your attention. I’d like to bring up the discussion of water changes, or furthermore, nutrient export. Many of us in the saltwater hobby (s***water? Is that a nono on here? Lol) rarely or never do water changes. Obviously we have the slight advantage of successfully skimming protein, as well as the tremendous useable surface area attainable with coral stone. Outside of that, we have the super macroalgea, chaeto, which does a tremendous job of this task as well. But really, 50% bi weekly water changes in freshwater vs. 10% monthly or less in saltwater doesn’t seem to be adding up. I may be missing some key elements to freshwater that I’m not aware of. Up until recently when I decided to get out of freshwater due to lack of time, I was doing 50% a week water changes. My goal before deciding to postpone my 375 build was to mimick the surface area found in coral stone with bioblocks. It is not uncommon to hear the opinion that nitrates are further broken down to nitrogen when there is a large colony of BB, which is exported by bubbling directly out of the tank when using such high volume media. I don’t know if this is true and am interested to see if this topic becomes more popular in the aquarium hobby in general. I had also planned on running a refugium of sorts, and figuring out the perfect plant to consume the excess nutrients. I never did get that far. I’d be interested to hear everyone’s thoughts
