Got aquarium water in liquid fert container - still safe to use?
I've been tinkering with an auto dosing setup to dose my ferts directly into my canister's output line. At first all seemed well, however after a couple days I noticed that not only were my check valves passing, but the pump rollers on my doser were installed incorrectly which allowed back siphoning. I ended up filling my dosing containers with aquarium water. I think I've got everything sorted now, however I'm unsure if the fertilizers are okay to use after they've had aquarium water sitting in them. Would there be any risk of harmful bacteria or something like that? Anyone know about this?
