SPS declining, not sure why.

I have seen the same. It was world Wide Corals who told me that they run very little and I may have too much and ever since I ran two pumps (mp40 + MP60) higher and two lower on LOW setting, I can grow anything. Prior, I couldn't even keep Pocci alive and I have 30+ years experience

Proof is in the rainbow pudding, huh? What is your turnover rate? I guess it’s one of those things where different tank, different conditions.

Turnover was 85%. Now it is ZERO. Also - I did go to Triton in this tank

Huh? Zero turn over? You have no water movement?

 

[Ashish Patel]

Turnover in %.. haha

I might not be on same page. Turnover as in loss? If so- yes, none the past few months. I have water movement BUT have all 4 heads turned down to minimums. I have nice movement yet, euphylias are waving in current and speaking of current, I also run twin Current Loop wavemakers at 1/3 power plus an icecap 3k in tank center at 20% power.

I have been slowly increasing my Radions at the rate of 1% every 2-3 weeks. I started at 50 percent few months back and now I am at 64. Par readings where most of my acros reside are 250-290ish...

I can tell you once I got up to 62-63 percent my acros starting taking off. They are enctusting and growing out and up.....

Haha, I mean turn over as in total water volume of display tank divided by gph of pumps in display.

Ahhh....360gallon. Pumps run at Approx 224 gph

Wow, that’s pretty low. Hard to believe it but your tank sure looks healthy.

I can only wish I couldn't keep Pocci alive. It is growing everywhere in my tank including on the back of a snail. How it got there I will never know.

Thanks for your post, which Radions are you running? Pro 4, etc.

IME 150-180 PAR is the best for new sps frags.. If given too much Par there more likely to fade and encrust like montis. The PAR 4 inches above these frags will be significantly higher and gives them insensitive to reach for the skys. Thats why my top frags are losers and the ones on the bottom are winners.

I too have noticed very different light preference between SPS FRAGS versus SPS colonies of the same species. Several things possibly at play to explain it,but my frags now get placed lower, and colonies (new or old) go higher. Personally, I am moving away from LED to T5. I borrowed a PAR meter that taught me A LOT about hotspots and coldspots in the top half of the tank with my LEDs.

As to the original question, I don't have your root cause. Aside from the modest swing in ALK, the numbers look fine to me. I don't think lighting is your root cause, but it can add stress. I dip and QT all new corals (Bayer, Lugol's), but I do believe dipping is stressful and another reason to re-acclimate to lighting.
Wishing you some happy corals!

I run a pair of mp40's on 100% reef crest 24/7. If I'm understanding, you are saying that's too much flow?

I was always under the impression that sps regardless of species can't have too much flow.
