Nacheetah calls the floating rocks creativity. We thought we would give it more character and decided to silicone the smaller rocks to the glass and eventually we will have some frags or something cool growing on them. As we are keeping an eye on the activity of the flow and current in the water we see that we have either alot of tiny bubbles or sand circulating or both. Evidence in the sump tells us it's fine sand because we have a thin layer of what appears to be sand at the bottom. We are debating if a smaller pump would do the job or doing away with the sand and maybe just having the larger crushed coral for the bottom.
According to the graph on our hammerhead pump, it is pushing around 4500 gls and is recommended for a 300-500 gl tank so maybe it's too big. We were told that it would work for our 125.
Any suggestions?
