I have an interesting stock of fish. All do well together with plenty of filteration with the water paremeters perfect. Again, My goal is to get the nitrates below 20ppm. So here is my stocking... (5) Roseline Sharks, (2) Rainbows, (7) tiger barbs, (2) Ruby barbs, (4) Gold Barbs, (2) Clown Loaches, (2) Common Plecos, (3) Malawi Cichlids and (3) Zebra Danios.
In my own research, all of the de-nitrate media options out there are not effective unless you have a very low flowrate filter. Not realistic without making a lot of mods to a filter.
The reason why I have avoided larger water changes is due to my Emperor filters not starting back up. Most times it requires a break down of the filters and tickering with them to work again. Not fun!
I'll start first with some of the "easy" and inexpensive plants as suggested earlier such as a Hornwort plant. Seems simple enough. I assume, I will have to stop using SeaChem's Neutral Regulator buffer!?! I hope now Co2 is needed for any of these plants. I do not need another expense or diy projects.
Thanks again for the help!
