Been looking at options at will be fitting one as soon as funds allow, came across this solution while looking about and think it could be a nice neat solution:
Submerged Surge tank with pump
Liking the idea of having the pump submerged as all I would need additionally is the teflon lines to the std lines and I'd probably fit an inline filter before the 044 pump to give a bit of extra protection. All in all does not look too much more than a decent Surge tank and pump in a more std configuration.
