At this point it is at experimental levels and I am only a year into the experiment with this type of system. I may very well be missing something but no person or fish has shown me what that might be exactly. All measurable perimeters are good and the fish are showing no signs of ill effects. I would like to point out that I DO advocate water frequent water changes on the average tank. I am simply experimenting with a natural way of filtering and at this point I have not found a need to do a water change with the way I have setup this system, but I am looking for that "missing link" that so many people keep telling me I must be missing. It seems to be more elusive than bigfoot and probably just as real. I have run my ideas by collage biology professors and they seem to be the only ones telling me to keep doing what I am doing because it makes sense. Oh well, what do they know, they are just the people that teach this stuff professionally.
I am not doing this experimenting because I am lazy and don't want to do water changes. It actually took allot of work to build these systems as I built everything except the pumps. I have been in this hobby for about 20 years and know water changing all to well.
Are you doing huge frequent water changes on your 6000g koi pond? If so, do you not feel this is a huge waist of water? Would you not prefer to have a filter system that drastically reduced the amount of water you waist? Or if you are not doing huge water changes, would you not like to have a filter system that reduces you maintenanceand at the same time improved the water quality? I spend less than half an hour per month dealing with my experimental tank, that includes feeding but minus all the testing I do and that tank waists NO water other than what is evaporated and I replenish.
I am planning a 2000g ray tank and do not want to waist ridiculous amounts of water doing huge water changes every week. So I am looking for a better way, a more natural way. So far my efforts seem to be paying off as my experiment is doing so well it astonishes me. I am simply trying to share my findings with people and I get people like you trying to "de-bunk" me. Like you said, to each there own, I will continue growing algae and doing what I can to advance my small part in this hobby and you keep doing your water changes.
You may have been in the hobby for 20 years, but the times have changed..
So while your fish live in the same water all the time, I will continue to give my fish fresh water.
I do not do drastic changes on the pond, as it's not done yet- and I won't once it's established, but there will be bi weekly water changes of at least 25%.
An indoor environment is so much different than an outdoor environment, so you can not compare the 2...
But because you have "more experience" I'll give you the win, buddy.
