Hijack. No worries if it helps others. All goodI don’t want to hijack Will’s thread, so I’ll keep it short. I think that koi pond is way too big for a QT setup even for your amount of fish. Keep it simple method is best. QT setups you’ll need to change the water every few weeks due to the ammonia spike. Changing 60-80g of water is not ideal. Check out HumbleFish for more methods of QT.
