this might be a odd question but i've got a high flow NEXT and i started to use DP Ultra just over 2 years ago.
now the high flow NEXT is telling me everything is a oke, 100% water quality conductivity is at 11.6 whatever that unit is.
i used to just do maintenance every year but then also made minor tweaks but for the past 2 years i've been content with my loop so i've been lazy and have not performed any maintenance (other then some dust busting) so i'm suprised everything seems good.is there anything i should probably be topping it up with? (growth/corrosion inhibiter) i mean i should probably just flush it and refresh it but i'm tempted to just let it run and see
