I did a water change yesterday and just tested the salinity today and it was 1.023.
My cleaner shrimp last I saw it was just laying on its side(Still aliveish) and then my basslet dragged it into the rocks. I'd imagine it's the drop from my normal 1.026 to 1.023 that caused the problem.
I can't figure out how the salinity got that low though. I tested the salinity the day before and it was 1.026. I tested the salinity of the water change water and it was 1.026. Both at about the same temp, both gave the refractometer a minute for the temps to adjust.
Poor little cleaner...
Put a bead of silicone from the top of the fence down to the bottom on each side of the path you want the water to follow. That should keep it contained in a stream so it falls back into the water.
I seriously doubt they'd work very well inline. More than a hint of head and they probably wouldn't flow anything at all. The same as streams and current seios. They're high flow, practically 0 head.
Either get a HOB overflow like Wasp suggests or get the tank drilled. Otherwise you're going to either be constantly checking and tweaking it to get the flows right or you're going to have wet floors.
This is stuck to a rock with a yellow Fiji leather from Pies. Some kind of sponge, maybe? The threads coming off it don't seem to retract like I'd expect if they were coral polyps.
All you can really do is make sure it's not vibrating against anything. Putting something around it will block any cooling and make it hot. Just learn to enjoy a nice 50 hertz hum.
Bassletts are good, wrasses, clowns, boxfish, tangs, damsels...Actually, now that I think about it, I can't think of more than a couple marine fish that AREN'T colorful.
I'm not quite clear on this...Is the water flowing out of the tank though that pipe or is the water coming FROM the pipe?
If it's leaving the tank through the pipe, you might be able to get more flow with a smaller pipe, but have it siphoning and using an air valve to tweak it to match the flow of the pump.
