Thanks bill, well i did something wrong. My crappies are dying. 3 inches of rain I'n two days, i guess they got caught I'n the water column with no o2. I have defuser over 18 ft , 8 ft down and been running it 3 hours before dawn. I made the mistake of putting it on bottom I'n 8 ft,,, not good ,,,, stird up the bottom to top. Rain for 4 days and cloudy ..... Wammo huge alge bloom. This is a learning curve Forsure. Lol..
