Thanks for the tips on the air pumps, much appreciated. I'll probably go with Air Force Pro one of these days.
So the system has been recirculating with tap water since Sunday, so almost 4 days. I just went down to check on things and to put the heater in the tent and noticed the water seems to have developed a little bit of a smell. It is circulating well, and there are air stones in each bucket including the res but the smell does seem to be coming from the water. I changed the water in the tray under the seedlings but I think the main system water is what is starting to smell. There are no plants or anything in it and the water temp is 69 degrees. PPM is roughly 260 which is what it was out of my tap and PH is 6.5. I did add some PH down to bring it there. Seems odd with as much movement in there as there is that it would smell.
Geez I haven't even got the little girls going in the water yet!
Also, they started getting really leggy so I turned up the light. Still got leggy, realized I had the timer set wrong and they were not getting enough light hours. Now set to 18hrs ON, 6 OFF and watching to see if I need to turn the lights up at all (dimmer).
