As my tap water is high in nitrates (20ppm) I am even wondering if it will be more beneficial as I treat the new water with Prime at every change.
Any thoughts on this?
first let me give you a really really nerdy equation:
amount just before water change=amount in replacement water+(buildup between water change)/(fraction of water change)
(this is after many many many water changes so that the value before each water change is the same)
So using your numbers:
So if you're say increasing nitrates at 1ppm/day and doing a 25% weekly water changes the nitrates just before a water change goes to:
10 liter per day:
So the key IMHO is to get the 1ppm/day down to 0. That way nitrates will always be 0 regardless of the water changes being done. Increasing the nitrate consumers with live plants does the very well.
I do not recommend prime or any other conditioners. Overdosed they kill the fish. Plus live plants control ammonia/nitrates with ver good side effects.
