Acropora issues

[10galtank]

A fan should help with the tank temp, although I wouldn't be super stressed, acropora generally like slightly higher temps then most corals. Not saying 30c is great for long periods, but before I had a chiller. my tank got up to 30c often in the summer. Did not lose any acro.

What are you dosing?
I found kalkwasser made a huge difference for me and things thrived on it and the ph boost is awesome!

I would also look at a ICP test to see if anything else is out of whack.

From my experience moving anything too fast with acro, stress RTN dead. Do not knee jerk react to parameter shifts, always amend slowly or trend, between a low and high point.

Phosphate swings I found did more damage then alk swings did both will cause RTN or STN! But can recover.

The other things I found that actually wiped all my acro out was, my RODI system filters expired and I did not get to it quick enough and so I was adding dirty unfiltered tap water and well, you guessed it RTN!
Fixed it with new filters and water changes and now everything is finally bouncing back (except the acro completely bleached every single one)

Get your fan going, send off a ICP to see if any minor elements are making your tank toxic. figure out what your dosing, what do you need to dose really.
Are you doing water changes?
filter some water and make up some fresh salt and do some water changes.
stay clear of marketing hype, cause most of it is garbage anyway.
I doubt the lights are an issue my corals have done well with kalkwasser, 2 part, and black box lights (although I have finally ordered some proper lights and waiting for delivery)

Thank you for the educated reply! To answer your questions, I dose All-For-Reef. It has been the one and only solution I have needed and have found great success with it in prior tanks. Water changes are frequent of mine, I use Bio-Actif salt. An ICP test would be nice here in the near future

What temp was that 13.5? Let's try eliminating temp as the cause.

Ambient temp is 78-79, no ceiling fan but two fans in room and yes is air conditioned. It is also a 40 breeder

This tank should not need a chiller. I would start by ensuring smoke surface agitation, and point a a/c vent toward the tank. Monitor for a few days, add a small fan blowing across the surface of water if needed. If that doesn't lower the temperature, then you need to evaluate humidity levels in your house. Too high and you won't gain much cooling from evaporation. Do you know how much water is added everyday for top off? And remember go slowly, don't need to drop the temperature in 2 hours.

Temp ran about the same, 80-83

Then temps likely not your issue.

Actually now thinking about it, what are you using to reduce phosphate levels? They are bouncing at pretty big rates, if your using GFO guarantee if your adding too much, you'll RTN your acro! Phosphates will do more damage then alk swings in my experience. .1 change in less then a day is quite a lot of difference

That’s exactly what I’m thinking. I run a fan on the tank, thinking of upgrading to a larger one. A chiller is unfortunately not an option for me.

Lower your AC temp?

 

[ryanjohn1]

IMO temp. I just had a healthy frag rtn from too many days @82-83. Can they take a bit of warm temps yes. But not for long.

Aside from high temp, focus on stability. 6/21 alk is 9.5, 6/24 it's 8.4. Whenever my alk starts swinging I'll sometimes lose something.

I had the temp issue in my 10ish gallon biocube. It was a 110v pump that was getting ready to depart this earth. I put the same pump you have on it and I didn’t need to run a fan anymore and my ATO headaches went away as a result also. 85 is way way too warm.

I do not run any GFO or phosphate intended removing chemical. I carbon dose with NP-Bacto Pellets and Bio Actif Salt. Has lowered PO4 dramatically within its time frame of use, prior levels were stable about 0.4ppm

Ac temp of house system stays at a steady 77

Roger that. My tank stayed a steady 9.5dkh for a good while but recently decided to drop it a bit to see if that has any result. This lower alk range you see is very “new” to my system.

Which pump are you referring to? Thank you

 

[bobnicaragua]

I think it’s the UV sterilizer driving up the temperature. Unplug it for a day or two and I bet your temperature drops.

Smart idea. It’s a 9w, think that pushes enough heat?

If I kept my room at this, I wouldn’t run a heater at all. I’d also unplug your heater. 77 is perfectly fine for acros.
