Reef Moonshiners Question

[Merge_595]

I almost always run carbon through a reactor but now since starting the Moonshiners program I'm thinking about maybe only running carbon a few day's once a month..watched a video on YouTube & Anand Kaimal from Coral Collections was running his carbon I think every 5 hours for 1 hour or something like that..what's your suggestions/opinions

You are worried about trace element removal? Or addition?

I think both of these effects just get incorporated into the many sources and sinks for trace elements and if you are dosing based off ICP to offset those effects, then it's not a problem.

I'd caution that the info supporting a single particular level of a trace element as being uniquely desirable is both inherently inaccurate (it ignores the chemical forms present with different bioavailability) and the fact that some have a very wide window of acceptability.

That said, if you want to run GAC intermittently, that's OK as long as you do not wait so long between uses that the water becomes anaerobic inside the GAC.

Thanks for the info. Worried about removal I run a small amount and change it every 2 weeks. Now that I'm doing ICP monthly is GAC necessary unless needed to remove something that's harmful?

GAC is used to remove organics. Dosing of trace elements by ICP does not change that reason. :)
