Re: Bottom drain to filter
#4
Sounds like a plan.
I should however point out that there are specific pumps for specific jobs, so for a pond filter you need a filter pump, filter pumps are designed to handle "solids" and pump them to the filter, and it is the job of the filter to catch and hold solids. Filter pumps send high volumes of water at low pressure to the filter, where as a fountain pump is designed to pump "clear water" (No solids) at great speed in order to operate the fountain nozzle.
If you use the wrong pump for the wrong task, it often will not work, I have seen people ask why a fountain nozzle does not work as the picture on the box shows, its because they have a filter pump, which is just not made for the task, I have also seen the opposite where people complain the pump blocks every day, its because they are using a fountain pump to supply a filter, fountain pumps can not handle solids, and soon block.
