Really hope someone can offer some advice please!
Basically, I have a 4 tank shrimp setup, one ontop of the other, top most around 5'10" off the ground at highest point. I'd like to have a simple overflow system on each tank, with a powered pump refill that I could plug in when I feel the need each week!
The idea is to have say 10% change done on each tank at the same time, each will be getting the same RO water (including mineral additives essential for the shrimp) from a ground level bucket I'd fill.
The overflow system I assume can be something similar to this (although much smaller as my tanks arent large)
The difficulty comes in the topping up part. I can see there are various submersible pumps, some that can push 6' high with variable outputs, but my concern is the bottom tank would fill much faster than the top tank. Perhaps I could ensure each had the same length of hose, but still guessing I'd need some sort of valve splitter? Any suggestions there? Also, the pumps seem to have a large hose output, so may have pressure issues if splitting 4 times into smaller hoses....
The outlet for the overflow I'd be running via hose out the back door into a ground drain so that part should be ok, but would need a closing off tap.
Has anyone achieved this sort of setup before and have any advice please?
Thanks in advance
