Thanks for checking the thread out muttley. Glad you got something out of it. I pretty much started this thread to keep track of what I'm doing and what I'm thinking about doing. Also, it's been great to get some of the more experienced and successful reefers come in here and make some comments and suggestions. I've learned a lot on this site. I try and research the best I can and make informed decisions that work for me and my tank.
Yeah, gotta take that camera apart at some point as well. I really wish I had it recently as I'd love to get a video of my cleaner shrimp climbing on the flame angel and giving her a massage.
As for the ORP? I don't exactly know 100%. I do think that it may have to do with several factors that are working against achieving a higher and stable ORP. One is my tank is fairly new and is stocked to early and hasn't really got stabilized yet. I'm still getting cyano blooms here and there along with diatom. I really didn't want this tank stocked so quickly with fish, but it is what it is.
Second, the ORP seems higher in the evening then it does in the morning and also is higher now that I have the surface really churning and cleaned up. So, to me that seems to indicate that it has something to do with air/oxygen exchange and/or PH as well.
Also, after I pulled that Algae out that had gone all mushyand the pods were munching on my ORP had plummeted down to 114 but several hours later it was back up to around 160 and climbing from there. So, I have to also believe because my tank is still maturing that any kind of detritus or dead organics is causing the ORP to drop rapidly then climb back up as it is filtered out biologically or mechanically.
