First tank related issue. The Fluval E series 300 watt just could not get tank temp up. It has stayed at the sane temp for days and has been showing 79 and blue despite being set much higher. The thermometer in the tank was only showing about 75. The 65B that I'm using is in the garage and while force air heated, it is not as warm as the house. I replaced it with an Aqueon pro 250 watt and it is actually heating.
So tank details for those interest in the equipment. 65B custom tank with 1\2" glass. Filter Aquaclear 110, Aqueon Pro 250 watt heater, Current USA satellite led (The cheap corded remote type)
