Saltwaterseahorses 35 gallon

I never thought to mention that if you could find a way to hook your tank up to about a 15g or 20g sump, you could go with a second pair of seahorses in that tank, but make sure they are from the same breeder as the first pair.
That would also allow you to put the rock, or most of it, in the sump, making it easier to keep the DT cleaner.
A lot of my tanks aren't drilled and on one I have a conventional DIY overflow hanging on the back and the other three have DIY PVC overlows.
