So water change Sunday (and skimmer clean obviously), thought I'd show you how I do my simple flow through water changes. Takes all of about 5 mins to do. I know flow through probably isn't the most efficient way of doing it but I'm lacking time these days so the simpler the better.
First up I turn off pretty much everything return pump, skimmer etc. Then close off all ball valves so only the main siphon is open, to stop the return siphoning back to the sump.
I then take the main siphon shown at the front here
The only part of the plumbing not glued, I pull it off and replace it with this
The hose runs out to a drain just outside. Then it's just a matter of pouring or pumping water into the dt. Everything that flows over the weir then ends up in the drain outside.
Replace the pipe on siphon, turn everything back on and retune the siphon and your done. Tuning the siphon just about takes me longer then the water change itself
