Hi im new here and I am from Cape Town, South Africa. Im building 6 ponds next to each other and they are all attached to each other in one line. See attached pics. I need the water to run or drip from the first pond to the second pond to the third and so forth. I will have one submersible pump to pump water from the last and lowest pond right back to the first pond. My question is does it matter if the ponds are different sizes and hold different volumes of water ?. I need the water to flow or drip from one pond to another and don't want to be stuck with ponds draining empty before the other is filled up if you know what I mean. help.\n\nThanx in advance.
