Hi all, I wouldn't mind your thoughts on my sump and water changes.
I'm in the process of finishing off my sump and am trying to work out a semi-automatic water change. I plan on having a 3 way valve on my return line to my DT from my sump.
I'd then have a pipe coming in from my new salt water mixing tank into the 3-way valve.
I'll also need to drill an overflow for the sump directly to drain.
So the process to do a water change would be:
1. Turn of main return pump to DT
2. Change the 3-way valve to select the NSW pipe
3. Turn on pump from NSW tank
4. NSW would then go into the DT
5. As the NSW displaced the water from the DT, the sump would fill up and start to overflow to drain
6. When NSW tank empty, turn off pump, change the 3-way vale back to the main return pump
7. Turn on the main return pump...and all done.
I've done a sketch of what I'm thinking below.
I have a concern around actually letting the sump essentially overfill and overflow (in a controlled manner) but as this is only whilst I'm doing a water change I reckon it would be ok for a short period of time.
Does anyone see any issues with what I'm planning?
