Thats right what I was thinking JCO. Have the temp at 78 for now and will start to drop it down to 72 over a few weeks. The 800 watt heater is working well and the fish have adjusted nicely although I came close to losing four on the initial stocking but was able to save them by separating them into a small bowl and adding extra air and a pinch of salt. They sprang back in minutes and now I have a few more fish then expected since they shipped extras

thanks for the advise all
