Yep hopefully water changes with system running, I have water supply right above where the sump is going, and will be running a drain outside.
Stocking will be from my 300l: 2x A.heckelii, plecs 3x L142, L200, L14, 3x Royal whiptails, fire eel (stunted to 20cm) plus what I decide on adding. Hoping to have some big sword plants as well
Not after gin clear water, I would prefer to have the ability to leave it for a couple of weeks and not have to worry.
