| Hi again JR,
Not sure what you mean by the first part of your question? But, in answer to the second... Without water changes, a showered pond's water will slowly deteriorate in it's suitability for keeping Koi healthy and growing. So, at the very least, you need to trickle water in (to overflow), so that water changes would in effect be equivalent to those carried out in a normal pond. But, the TDS meter is the tool for measuring whether these changes are enough, or more than needed.
Time for beddiebyes now. See you later...
Goodnight,
Mike. |
