need help with noisy pipes please

[lastlight]

I'm sure it means a lot less flow. But when I 'pop the hood' it makes me happy hehe.

I've reduced flow for now in both tanks so that full siphons can't form. I'm sure I don't need much in either. The water-change tank simply needs to run inline and provide me with 20 gallons to change out weekly that's got the same chemistry as the rest of the tank. The pods in the fuge certainly don't need more than a trickle either I'm guessing.

What I might also do later is use a few inches of flex hose on each outlet into the sump so the water enters more smoothly.
