Plumbing the pond with a big?

[RedRunner]

Your electrical outlet should have an in-use cover. It's a plastic cover that allows you to close it (while you have things plugged in), protecting the outlet from the weather. There's a removable notch on the bottom of the cover where the wires can exit.
I see that your outlet is not a GFCI. Is it perhaps protected by a GFCI circuit breaker or feed by another GFCI outlet? A GFCI protected outlet is a must and is required by code. Please tell me it's protected...

The outlet is running off of a gcfi at the house. If I put it near the pond that thing would be tripping all the time. I haven’t had any issues, I plan on putting a faux rock over it, the skimmer, and the air pump. I have to save up to get this faux rock, it will be insulated and have vents.

Retaining wall for the bog? Over time it will get full of muck, debris and then the water flow out will slow down.

We will see. Maybe that will work in my favor maybe not.

When you order the wye get a double one so that you can split the water evenly. You will have to add a cap to block off the unused outlet. Also, take out any twists or bends on the pipe coming out of the pump. If possible swap out that black tubing with a flexible pipe that can be glued on to the PVC. You have a lot of resistance in your setup. Water is going to take the least resistance and it would appear that it likes the flow going to the bog . One other thing if you need a 90 degree turn use long sweep 90 degree fittings and not regular 90 degree.
