NEW SKIMMER
The new little SC-65 skimmer's working out well. Got it tuned to pull skimmate that appears about as dark/thick as I was getting from the Tunze. But it's consistently pulling many times the volume. The only downside to that is having to clean the cup 2-3 times a week vs. once. It's not a volume problem, but the neck just gets nasty.
NEW FISH
And I got some Apogon parvulus - Redspot Cardinalfish. Two orders really. Both lots of five. Seven remain. One was DOA, two have disappeared. I'm not sure if that succumbing to long term stress from the shipping, victims of my tube anemone, or jumping. But the population's been stable for weeks now, so I was hoping that there would be no more losses.
However, I've noticed that two are noticably thin, and swimming with their caudal (tail) fins clamped. Not good. I'm feeding generously 3 times a day, so I'd like to think it's not starvation. Not really sure what's wrong.
NEW MP10 DRY SIDE
I tried to change the bearings on my oldest MP10 dry side. It was like sixth one ever made (really) and it was NOISY. But I made a mess of trying to swap out the bearings. Ruined the piece. You can read about it here.
But I bought a new drys side, and it is SILENT. Wow! What a difference.
NEW IN-SUMP RETURN HOSES
My original return hoses in the sump were 1/2", thick reinforced tubing. And clear. That was the problem part. You can see them (unattached to anything by the bulkhead) in this post.
Over time the light of the ATS has been shining on the leftmost one, and it has become almost totally clogged with algae. So I got some black silicone tubing from AvastMarine, and swapped it out. I assumed that I'd be able to reuse the clamps I had on the old tubing, but the AvastMarine tubing walls were so thin (too thin really), I had to swap them out. Fortunately I had just the right side on hand in my spare parts supply.
APEX TEMP AND PHOTO PERIOD CHANGES
The Apex has seasonal features that - depending on the day of the year - adjust your tank temp and photo period as if your tank was a typical tropical reef at 15° north latitude. And it allows offsets, so my lights can come on a desired time after sunrise (would be at 15° north latitude), and turn off a desired time after sunset - allows for night viewing. Same with temp - I keep my tank a shade warmer than said tropical reef, but it allows offsets. So while my tank is not quite as cool, its temp swings a tiny shade daily in tune with nature's ocean temperature cycles.
Which BTW, this actually changes my overall photo period very little most of the year, mostly just the on/off times. But over the course of a year the longest day will be around 45 minutes longer than my old photo period, and the shortest day around 45 minutes shorter.
VORTECH FLOW CHANGES
When I first put up the tank I had the Vortechs programmed (with the Apex) to alter their flow throughout the day. But I was using the Lagoon setting for most of the day, except for using the Reef Crest setting at the peak of the photo period. Now I've changed that to Reef Crest all day, and all night. Reef Crest is much more random. Plus I "anti-synched" one Vortech with the other. So if one is blowing hard, the other's blowing soft. Seems to be giving a much more random flow.
And I used to alter the flow dramatically from mid-day to night with flow rated changing from a peaceful 20% at night to 80% at mid-day. Now it slides from 60% to 80%. I'm trying to see if this makes my SPS happier. If so, I'll try 70% to 100% next.
So it's watch an wait on the Cardinalfish. And I'm looking forward to seeing how the SPS respond to these adjustments. Everything BUT the SPS is happy. SPS... the jury is still out.
