Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
Sorry to see you taking a break.
Do you travel by AO any time during the week? I need or could use one of the MH reflectors. Is it 4 of them on a rail? I'll take it. I have to go to AO this Fri.
I bought a used complete 120 gallon tank, stand, canopy and tons of equipment this weekend to setup another system. By the time I got home from only an hour drive, We were unloading the tank and noticed a crack down the back. It wasn't cracked when we loaded it. Not sure if it cracked from heat...
^ This is most likely the problem. You might not see the green light because the sensor is shot. I just had a sensor replaced in a customers house for about the $150 you said. It was doing the exact thing your's does.
