Hi everyone, been forever and a day since I've been on, I broke down all my aquariums a few years back when I got married/kids/different home/etc. ANYWAY.....
I moved into a house that has a koi pond, they had removed the fish when they listed it last fall. I have left it running for all the reasons it should, and now I am interested in putting in new koi.
The system is fairly typical, with the horse tub bio filter(rocks and bioballs) with one pump, standard waterfall with a closed-loop pump. The tub is 2/3 full of stone and bio-balls, so it can hold a lot of material. I recently did a basic overhaul/cleaning, but never drained the filter system or added any chemicals. It's got sufficient 'muck' for me to believe that plenty of fish-in existing bacteria is still present. I occasionally have decaying matter in the pond, dead leaves, the occasional dead frog I didn't catch in time(they got through holes in the net and couldn't get out), and a lot of earthworms make their way in to their demise. I've finally had time to entertain fish. I bought another new API full pond test kit and am familiar with the natural cycle. I haven't tested the water yet, but I expect the conditions to show somewhere around 'acceptable for fish'.
However, my main question is, are my test results going to be accurate for fish? As I've had nothing living in there(on purpose).
I was thinking that maybe I should add some ammonia first to see if the pond reacts and tries to process it or triggers a cycle. Most questions I can find involve new pond setup or caring for just added fish on an as-yet uncycled pond system. I have a feeling that I should still have bacteria present that would fast cycle if 'challenged' with waste product. I'm hoping it would be cycled, but I don't want to do water changes on pond. My guesstimate is it is roughly 675-720 gallons. I just don't want it test OK and then have chaos when I add fish/ammonia. It's not like chasing a cycle on a 30 gallon bowfront Any thoughts or help is appreciated.
