Well I have an ozone generator I was going to hook up to the system to see if better water clarity would have any beneficial effects. ORP ran pretty much between 340mV and 380mV or so, but generally at the lower end of that range.
A little less than a week ago I made the pappone recipe and started to feed it in the morning when I did the first fish feeding. I used repurposed frozen mysid trays for the cubes. So far I've added one cube per day after skipping the second day, wanting to see what the reaction would be from the initial feeding - looked for recommendations and cube sizes for feeding, but no one was really clear on that. System water volume is about 709L so I figured the small mysid cubes would be ok.
Hmmm? Not sure I need the ozone. Water clarity has never been better. I am wondering when I need to be concerned about the ORP reading though. How high might be too high or will this self-limit? I think Randy said if not adding "oxidizers like ozone" then ORP shouldn't be a concern, but just being cautious here.
You can see when the first feeding took place as it dropped ORP pretty drastically, but from that point on it's been climbing steadily. I used the reference solution for checking the probe a few months ago when the tank was commissioned and have kept the probe clean. However that doesn't mean the reading is accurate but it does mean the readings are relative.
After the feeding, corals have their sweepers out feeding from the water column. I have not use amino acid dosing in conjunction with the pappone. The recipe I used also does not have HGH and I used less sugar than the recipe called for. Recipe posted calls for 1tbs and I used 1tsp.
Guess I can only observe and see where this goes. So far only one coral may have reacted negatively to this. It was an acro that was always brown - growing but never colored up. Now it may be lost. However all other corals look pretty good and LPS really seem to be responding well.
