How do I build a trickle tower? Could I just add some green matting on the top of my sand/gravel barrel filter and add bacteria? I put a bid on a bio/mechanical/uv filter on ebay for a 6,000 gallon pond last night. Plan to put that in line with my barrel filter, I'm assuming I should install this after the barrel and not before? Again, can the salt be plain farm salt or is pond salt special? How much salt should I add? Sun is on the water 50-70% of the time, no plants as I wanted to only have koi. Pond has been running since May, I have about 13 koi, ranging in size from 8-24 inches. I also seem to have had a spawn recently as lots of little minnows everywhere. Pond is 5 feet at the deepest, 3 feet at the shallowest, long and skinny with a big waterfall coming out of the barrel. Pump puts out about 2,000 gallons an hour. I will admit I was only doing a water change about once a month or less, not knowing it was necessary, but the fish have flourished until the algae chemical I mistakenly tried this week. I assume that with the extreme heat we get in the summer in Oklahoma that I will not be able to keep the algae down without a UV filter and I've noticed all the big places I've visited have used them with crystal clear water. Do I need to continue weekly 20% changes with this setup once the pond matures and the algae dies down, temperatures gets lower? My water temp is now in the 70sF. Thanks, this is a great forum, glad I found it before it was too late!!!!!
