SPS acros dying from tips.

That event obviously caused it but I doubt it was the alk value
What else were you too tired to test? Salinity? Temp? If you put an over sized heater in the Rubbermaid the temp could of spiked to 85 or more, even with the built in thermostat.
I'm sure there are torts and stags that can withstand a drastic alk swing. Not willing to try it with my Tenuis. Again, your example of a 1-2 dkh swing isn't the same as a huge spike.
No heater. It was summer. And of course I tested salinity while mixing new water.

I dont play rushing roulette with my tanks when it comes to alk control, any hobbyist in the game as long as you should no that's the wrong info to give anyone dealing with Acropora. Alk control is one of the big contributors to rtn'ing in Acropora because of the stability required for their hospitality. You might can get away with said results in LPS, but not with Acropora. Their not that forgiving. I dont use my trident apex doser because of the inconsistency of its numbers. My old cheap jaebo doser works just fine for me, I rather dial in my numbers manually anyway from my own cognitive than rely on a machine to malfunction and overdose. No offense to anyone that use apex for dosing, just my preference. To each their own!Here’s the last 3 months

Sooooo you didn’t have any torts or stags in that pile?? I’m not saying a stable alk is a bad thing. I’m just saying blaming a mass acro death event on an 1 dkh swing is wrong. Like some suggested to the OP in this thread. My Tenuis were exposed to 40 dKh overnight btw. Not something I would deliberately do again, but they were fine. Just like when we recently lost power and the temp dropped from 80 to 69 in 5 hours before I set up my generator, and again, all Tenuis were fine.
You’re saying I can’t get away with what I’ve already got away with?
These aren’t buy 7 for $110

Dont hate on my giveaways.

Third one looks familiar
I had to relocate mine bc it was too large and not worth the space it was taking up
But that wasn’t the point. How do you explain my corals if alk swings kill acros?
What’s the first pic btw? RRU angry Bird? From TSA?
Never mind. Doesn’t have the correct axial corallite. Tsa ghostrider?

I think some corals (colonies) can handle larger Alk swings. I have a couple of larger acros that look ok right now while my smaller frags are dying. In this case, SIZE MATTERS!
@Charlie’s Frags - When did you start keeping all soft coral and LPS?You’re saying I can’t get away with what I’ve already got away with?

I think alkalinity swings can adversely effect an otherwise unhealthy coral.
I have, for instance, purchased a coral from an LFS that maintains high alk (e.g. Instant Ocean) and plopped the coral in a low alk environment (e.g. Tropic Marin Pro), creating an instant alk swing, without apparent issues. Having that said, I recommend trying to keep stable alk. That’s less important when you only keep soft coral and LPS like @Charlie’s Frags and @Scott b
I too have butt-dialed a liter of alkalinity into my frag system and only lost an acan. I was very surprised. I won't say my sticks were real happy about it; I didn't have PE for a few days, but everything pulled through.
I do believe a material ALK swing is a source of stress. Perhaps when it is paired with lower nutrient, or some other pre-existing condition, it becomes the final straw. Come to think of it, that acan was in the frag system due to injury after laying facedown on the sand for ... a time.
Thanks @Rick5 that picture was taken right before I tore the reef apart last summer. It became too crowded, shaded and choked for flow.
As to ALK, mine ranges 7.7 to 8.5 in each system. I use IORC salt which mixes to 10.5, so I get a bump at each water change. If I am doing a bigger WC I will knock down the ALK a bit.

After reviewing your "SPS Nightmare" thread, it seems that you did in fact suffer some losses from the alk spike, 2 acros died. So, do you suppose they died from the alk spike or did you forget to check temp and salinity?
What did I say about those? I’m not looking at the thread but the 2 frags were mostly dead already. They were an sc op frag and a Tgc rainbow feast that had Stn and zero PE before the event.After reviewing your "SPS Nightmare" thread, it seems that you did in fact suffer some losses from the alk spike, 2 acros died.

The other 50 acros were as good as ever.
Is that all you got @Kattkrazie
Wow. That’s dedication.After reviewing your "SPS Nightmare" thread, it seems that you did in fact suffer some losses from the alk spike, 2 acros died. So, do you suppose they died from the alk spike or did you forget to check temp and salinity?
