I do have a sump and it enters the sump above the water line. however, there is no splashing. I have turned a 90* elbow facing up and allow the water to flow over. Its not rushing so its a smooth transition. my sump is set-up as
fuge->return<-skimmer.
I need to post pics so you can see but i am just to lazy.
I think maybe it was that one section of pipe I forgot to glue up. But still I need an RO/DI unit. Buying water each week is going to start adding up and that is money I could be saving towards a good unit from purewaterclub.com that I want.
