How can you not import the nutrients that will eventually need to be removed?
Sorry I can see how that would be unclear. Basically the key is effort, make certain that your using as pure a water possible for top off, don't overfeed, wash/soak foods in
RO/
DI water to remove as much phosphate from them and then drain off the water, don't add garbage to your tank (like most trace supplaments) if you don't know that it is necessary and exactly what it does. If your not doing waterchanges...don't add an all encompassing supplament for traces, add individual traces that you can test for and you know the system needs. Etc...As noted, you cannot avoid adding nutrients to your system, but with a little effort you can minimize this. For example, I got an
RO/
DI last week with a drinking water kit. The
DI was bad and haven't recieved the new one yet. The water out of the drinking water faucet sits in a bladder tank until used, that water reads 16ppm
TDS, the water coming out of the
DI hose comes out at 11
ppm TDS. Not a huge difference, but if I weren't doing water changes, that 5
ppm TDS, would be enough for me to go to the effort to get my topoff water from the
DI hose rather than the faucet. The faucet is easier though and since I do water changes, I am lazy and get it from the faucet.
