So, correct me if I am wrong:
I am reading that if I keep up on weekly 10% water changes, I don't need any of this other stuff. The additional stuff can make the water better, but is not absolutely necessary. I can run a completely empty HOB
filter, using it for water flow only (no other powerheads). If I am willing to put in the manual work to change water each week, and not overstock, I can save money by not having to get these other items. I can run a pretty stripped down tank without being cruel to my inhabitants.
Of course, this is all may be true if nitrates are low enough. I know 0 nitrates is the ideal, but what is really reasonable? At what level would I need to do more than weekly water changes? 5? 10? 20? 40?
Finally, it sounds as if a 30 gallon tank could be set up about the same way, since they are both considered "nano". Whatever works for my 10 will likely be duplicated for a 30 down the road (with the addtion of an RO
I am not trying to sound cheap. Lots of things would be beneficial, but not everything is necessary. I want to start simple and add what is needed based on water parameters.
That said: it sounds like you would use seachem matrix over purigen to remove phosphates, even though it is meant for canisters
Thanks so much!
