I was not advocating the "shrimp now" method your referring to... my point was that there are no substitutes for water changes.
Plain & Simple
Your dealing with a closed system inside your aquarium, your plant bio-mass
and potions will serve to detoxify the Ammonium compounds in the water...
but the only way to completely remove them from your system is to perform
periodic water changes. (via dilution as you pointed out).
In reading your initial post, I *mistakenly* assumed you were trying to cycle your tank with no water changes (as I saw no reference to them)... My bad!
Reading your subsequent posts I see that you have a plan that includes
regular partial water changes...
I've seen alot of products the purport to replace the need for WCs
(and other regular maintainance duties) come and go in the ~42 years
since I started my first aquarium... a few actually even worked to some degree
(most however are nothing more than snake oil) but none of them could come even close to replicating the benefits of a simple water change.
I'll stop typing now (sound of fat old guy dismounting soap box here)
Be sure to share some pics of your tank with us.. we like pics around here
