Ok I am about to complete my Closed loop system tommarrow, I am still waiting for my sump/refuge..but teh top end is plumbed. So onec I receive my sump I will plumb teh drain and plumb my open system pump. So what is the next step? The unit will be shoved against the wall when done , giving me limited space to fix things. Should I fill the tank up now, test the plumbing and then drain to move back into place? If so should I do a tap water test or test with salt water? I am worried if I do a tap water test, the water would remain in my CL system and haunt me later....please someone give me some direction?

Thanks

I figured it would be best, + less messy if you have a leak....I just didn't want to risk leaving any unwanted elements as I am usually anal about using RO water..


thanks guys
