Three 1/8" overflow holes per 5 gl SIP

In your photos, it appears your drainage (overflow) holes are positioned just above the platform. Mine are typically 1/2 inch below the platform.
Thoughts or insight?
Thanks,

Actually, there are three (3) 1/8" overflow drains in each 5 gl bucket. They are hard to see in a photo, especially on a black bucket.
Just below every other 7/8" drainage holes, the 1/8" holes are drilled 1/4" down. The coroplast also can be seen thru that overflow hole, if you look straight on.
By drilling 3 holes every other drain hole, the customer is quaranteed that if the bucket bottom is not level, there will always be a overflow hole that will overflow.
In my 25 gl, round tubs, there are 8 drain holes, and 4 overflow holes.
I, always laugh, when I, see people that drill a lot of holes in thier bottoms of thier buckets and call them drain holes. The water is wicked from the bottom, not poured in from the top.
The media is moist, not wet, at the bottom of the container, so no it doesn't form water per se, that needs draining.
Aeration holes are another laugh. Thats a marketing gimmick.
How does the air get into the bottom of the bucket, once the water is wicked up to the media in the first place.
What force will react with air that isn't moving, move it up thru the aeration holes.
Air fills the reservoir void as the water level drops, thru the path of least resistance. That's either thru the overflow holes, or the fill tube.
I'm going to do a demo, of this tommorrow. you will be able to see the air moving up between the inside of walls of 2 buckets.
You will be able to see the air flowing thru the overflow drains, and the fill tube, when the reservoir is being refilled.
