RTN, Acro eating flatworm, alkalinity burn, bleaching? (1 Viewer)

[oneasianguy]

Does anyone know what this might be? One if my Acro is turning more and more white and my other encrusting Monti got some white spots on it as well.
Got a few ideas to what might caused this:
1. Rapid tissue necrosis
2. Alkalinity burn
3. Light bleaching
4. Acro eating flatworm (worst case)

What are your parameters? Alk, Ca, Mg, NO3, PO4, Salinity?

Acro white areas are dead. Looks like slow STN but just depends on how quickly you saw it.

Not sure on monti.

If the dead one a strawberry shortcake? If so, they are suoer sensitive. I've had a whole colony go up on me before... But they make great canaries for telling you something is not right with the system.

Alk 8.5
Calcium 400
Mag 1300
salinity 1.024
Nitrate 10
Phosphate 0.25

I am not sure what that is that got the RTN. Maybe red planet? It was a small piece and encrusted that patch of rock. Then turned white.

I'd bump up Mg to 1400 ppm and get your phosphate down. I keep mine at 0.03 ppm for a predominantly SPS tank. If yours is the same and the 0.25 ppm isn't a typo, I'd say that's your problem right there.... But That's just my opinion.

Keep in mind to lower the phosphate level slowly... Lowering it too fast can make the situation 10x worse.

Agree with Ty, keep my nitrates and phosphates below .05

Sounds good. I will try to do that and see if the condition improves.

Also a good of chance of monti eating nudibranch. It's one of the hardest pest to get rid of. Best option is to remove all montis from the tank for a period of time.

I like you asked for the NO3 and PO4 as well as the main three (Alk Cal Mag).

Nitrates are too bad, but the PO4 is just a little high for SPS tank. I think you’ll enjoy much better colors if you get them under 0.1 and preferably 0.009 to 0.7 range. Other corals would enjoy the levels just where they are, but those darn ACROS!

What about Red bugs?? Have you looked really good at the corals at night?

 

[Reefahholic]

Nitrates aren't**

 

[Reefahholic]

Listen too this guy talk about his tank.

Nitrates are 30 and PO4 is 0.3.

Tank looks amazing, but would look even better if he lowered both levels quite a bit. A 2-3 year old tank will handle it quite well short term, but will eventually decline and spiral out of control if the levels continue to rise any higher and aren’t corrected. His tank is well managed as far as tank husbandry is concearned. Not to mention it’s probably about 2-3 years mature. Like you, he noticed that something wasn’t quite right- tested the water chemistry- and will now make an effort to correct the problem.

You might wanna send a triton test to rule out any faulty equipment like a bad powerhead, heater, magnet, etc.. that’s corroded in the tank. Just to have piece of mind.
