Daplatapus's upgrade

[daplatapus]

The other question I had (it just came back to me) is for those running dual siphon's. Is it hard to balance? Should I be tying them together and controlling with one gate valve? I know if I do it that way all the piping has to be exactly the same length, but it seems better to have redundancy with 2 separate drains. Just not sure how hard it will be to balance. What think you?
