Some updates.
On 6/23 I dosed another round of Prazi and started to feed the Anti Parasite Quad Flakes instead of the General Trio Flake. This was based on none of the other fish except for the Flame Angel that died showing any signs of a bacterial infection. The Lubbock's Wrasse had some white poop and there was also some flashing by the yellow wrasse and blue damsel but not a lot. none of the remaining fish were eating aggressively at all.
On 6/25 the McCosker's Wrasse and Neon Dottyback both died. There were no signs of a bacterial infection that I could see. Flukes or another internal parasite seems more likely.
On 6/28 I dosed Prazi again. No other losses and still no normal feeding responses.
After 10 days of the Anti Parasite Quad Flakes I started feeding regular food again on 7/3. Again, nobody is eating aggressively but there is no more flashing and things seem to have stabilized.
On 7/4 I did a water change and turned the skimmer back on. The water has been cloudy for a day or two, not sure why. Possible bacteria bloom. Turned on the UV for the first time to see if that helps clear the water.
7/8. the water has cleared. I used a turkey baster to stir things up again and that also cleared pretty quickly. Not sure if to was the uv or not but figured turning it on couldn't hurt at this point.
I may have caused the cloudy water by stirring up the detritus that's in the fleece roller. I've been letting it sit to see how long it would take to clog enough to trigger the automatic advancement of the fleece. It was finally starting to back up enough to do that but the sensor is slightly higher than the emergency overflow for the chamber its in so the water can't get high enough to trigger the advance. I think a lot of detritus had built up in there and at one point I had tried to reposition the filter roller body to make sure there wasn't any bypass going on. The sump chambers got real dirty right after I did that so I think I knocked a bunch of detritus loose instead of manually advancing the roller to remove it from the tank. I'm going to try two things with the filter roller. First I'm going to have a custom 3d printed collar made that fits the sock opening better. Right now the ones that came with the roller are either slightly too large or too small to fit the opening. I'm using the slightly larger one and it makes he unit sit up a little too high for the sensor to get triggered. If that doesn't solve the problem then I'll get the upgrade kit from Coralvue that allows the sensor to be magnet mounted to the baffle wall instead of attached to the body of the fleece roller. This will allow me to choose the water height that triggers the sensor and advances the fleece. One for both of those things should solve that problem.
As of today things seem better. The fish are eating a little bit better. Still not attacking food the way I like to see them do it but better than a few days ago. No signs of flashing, white poop or white blotches. The yellow wrasse picks at the sand a lot so it may be snacking on pods that I just can't see. It has grown a little in the last few weeks. The Lubbock's wrasse seems less lethargic than it was looking a week ago. The filefish and the blue damsel just keep doing their thing and have mostly seemed unaffected by whatever was going on that killed the other fish. If things keep going in this direction I will move the Tomini Tang over within the next 7-10 days and get the Clown and leftover corals in the Lagoon 50 moved down to the garage tank. Once I clear the Lagoon 50 I can move the Apex and ATO over to the new tank and then finish off the wire management. It will be good to get that done so I can get the old tank out of the room and start really whipping my office into shape.
Lastly, the macro and sponges on the live rock are hanging in there but not thriving.
This was to be expected since I'm just using natural sunlight and ambient room light right now. This tank does not yet have the Neptune Sky's turned on and won't for a while. I just want to let the rocks mature and keep the uglies to a minimum if I can. So far there has been some build up on the side panels but not much. I've only scraped them once or twice since the tank got wet. There are no signs of diatoms or anything else on the Stax Rocks that make up most of the scape yet, they are still lilly white. The tank is pretty clean and there have been no nutrient spikes.
