Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
@Stephen8169301 make the images Medium next time, taking up the whole screen so its hard to see!
Is that an acro in a new tank? Keep us updated on progress~!
There is an app on iPhone called "Photone", there is a $5 module that helps you read full spectrum par. Ziplock your phone, dunk the phone and get some par readings
My memory is a bit hazy on this, and I just may be throwing out names. But potassium chloride or some other chemical dipping compound has some anecdotal evidence on it. On Facebook, find chummingham, you may be able to ask him cause I think it was a video I saw where he talked about it
With regards to the GKM, be aware of rising levels of antimony. I wouldn't use it long term if you can find something better. Look on R2R for multiple threads on this
i dont own one, but i've used the iphone app "photone" before.. requires a $5 purchase for the full spectrum but its been compared to some of the other popular par meters with some really good results.. check R2R
