Hey guys my name is Carlos and I'm new to this forum and to the aquarium hobby as well. Right now I have an outdoor 40 gallon glass aquarium; its housing a 4-inch western-painted turtle, 2-inch three-stripe mud turtle, two koi about 3-4 inches and a 6-inch common plecostomus. For the filter I'm using the Tetra Whisper 40i (up to 40 gallons) internal power-filter and I recently installed the Tetra AP 150 Air Pump (up to 150 gallons) before bringing the second koi and the pleco home.
Like a mentioned before the tank it's outside, it gets about 5 hours of direct sunlight on the water's surface for my turtles to bask. The side of the glass facing the sun is always covered so the fish have shade. Anyways the temperature during the day fluctuates from 80-84F or so my cheap $5 dollar thermometer says, the water is always cool during the day, never warm. I do have a 250 watt water heater from Aqueon that goes on at night to keep the temp at 76F.
The filter is elevated to create more water movement and oxygen.
That's the airstone working tirelessly.
Just some pics.
From what I understand the higher the tempature, the less oxygen, hence why I bought such a powerful Air Pump in comparison to the tank size. Can I turn off the airpump during the night when the water is cooler, will the growing kois and pleco have enough oxygen with just the filter's waterfall movement? I don't want to keep the air pump running 24 hours a day.
PS: I live in Florida.
