freshwater top offs
I was wondering what the best way to add top off water to a sumpless system would be? I've been slowely pouring the water in the tank,using my hand to distribute it. would that be bad for a fish or coral to swim in some water whos salinity is far less than normal? like if a fish was swimming along and it ran through a pocket of freshwater would that be bad? How slowely should i add it so as not to create to big of a salinity swing? the water has been evaporating very quickly.
Also, i bought some lr rubble to put in the powerfilter and i was wondering if i should take some fins off the filters impelor so slow down the flow? You know cut off every other blade. Is there anything else i could put in the powerfilter besides lr rubble?
And for some good news. I found some of these little feather dustes on my rock! How big to they get? I am also geting some awsome algea growth. the rock is exelent quality, i bought it localy and its from waltsmith and its is so light and has so many caves.
