Re: [APD] re water changes

I've got kind of a stupid question. I know for sure that one of the reasons
to we do water changes in a established tank is to reduce the nitrate level
in your tank. But what happens when you put a lot of fast growing plants in
your tank? I would think that these undemanding plants will use up the
excess nitrates.

You can just add more water as it evaporates from the tank and fertilizer
for the plants. Do you still need to do water changes in this case?


I've got alot of plant estate in my tank and nitrate levels as I've recently discovered are high every other week. If you had enough quick growning plants to absorb all the nitrates, you'd then have to add to keep the plants going. With suffient filteration as required to keep the tank healthy, I don't personally think it's possible to achieve 0 nitrates through plant absorption.
