I got the PSK 150 and I about 20 minutes after install it was pulling out a bunch of green gobbley gunk.

Now a newbie question: If I run it wet, do I need to replace with salt or r/o water? It makes sense to replace with salt, but I wasn't 100%.

Thanks

You would replace with salt, but honestly you shouldn't be pulling out that much skimmate that it will really affect your salinity levels too much. Try not topping off to replace it and chart your salinity. If it starts to fall then start topping off. Another way around it is to mix up your water change water at a very slightly higher level than your tank. Say your keeping your tank at 1.025 sg. Mix your water change water to 1.026. Again checking this often helps. If you have a refractometer checking is reaally quick.
