Tank level question

Well was starting a test overflow/ drain then found out one ot the bulkheads was cracked, great so I drained the overflow out and removed the standpipe. Now here is my question, the tank is less then a 1/4" out of level in 6' but because of this only one overflow wants to flow. Now when I replace this bulkhead and standpipe I am thinking about moving the standpipe up about 1/4-3/8" to compensate to the slight out of levelness of the tank. I ahve releveled it 3 times and this is as close as I seem to get before doing the back and forth thing. Would my adjusting the standpipe slightly fix this as this would allow the water level to be slightly higher in this overflow box?

Composite shims as they don't compress like cedar shims do

 

They are wedge shape so I can stack them as needed to get the right thickness if I keep releveling jsut have to drain the tank again to do so and need to line up som help to do it.






 

 

SW CR not far from pets playhouse. Tank isn't that far out of level that I would need 2x4s, from end to end atmost 1/2" total in 6', I have it shimmed some just need to shim a bit more, you want to come help? lol

 

Ah that makes more sense. After 6 hours of plumbing the tank I'm a bit out of it. Must be time to sleep. pm incoming
