set up new aquarium
I had baby koi in an outdoor water feature (oak barrel with a plastic tub/liner in it)over the summer. There are 3 koi, each being 3" long. Now, I need to bring in the koi for winter because it is getting down to 5C - 10C at night these days. I set up the 20 year old 11"wide x 29"long x 10"(water depth) aquarium this weekend, adding fresh tap water, got the chemical filter running (with well-rinsed activated charcoal in one section and filter "cotton batton" in the other), and added the water lettuce from the pond with a gallon of pond water also. My question to everyone out there...how soon can I add my koi? I did not add cholorine de... stuff to the water and so was wondering how long, with a filter going, does it take to clear the water of cholorine? Also, if I bring in some water from the tub outside with the koi, will that be good for the koi or the water? Should I bring in 1/2 the water from the tub? Also, how much light should I give the water lettuce? I need to buy new bulbs.
