That is the only thing that has changed.
That being said, I still think a DSB works, but given my experiance, I now think you really need to change out the DSB every now and then.
When we moved and I removed the DSB, I cant tell you how much crap got reliesed into the water column. It was quite nasty.
The only other thing is I was running 1.25 and now I am at 1.23, but this is with a cheap hydrometer.
I am getting ready to buy a good refractometer so I will let you know what the ACTUAL salinity is later.
