This was INSANELY helpful. It helped me get a grasp on keeping sps. Halfway through I had a question and was going to make a comment, but you answered it. That's how you know you answered just about everything....job well done Travis😉👍👏

I could not believe this when you showed it to me. I enjoy how you take everyone through a step by step process in dealing with this issue. Great job...☺👍

Great video. I would say that knee jerk reactions are probably one of the top 5 problems new reefers do wrong. I know it was my issue 🤦🏼‍♂️

Thanks for making the video. It makes a lot of sense about not cutting the STN part off, although all the other advice was to cut and glue the part to stop further spread. That's never worked for me, so I'll keep the water stable and leave it the hell alone. It's so obvious now you've said it.

Really informative. I know you could do tons of videos of this kind and hope you continue to do so. Thanks for the video.

Low Iodine can cause that to and bleaching where light hits ofc.

Very helpful video with tons of great information, as usual. Keep up the great content Travis!

I’d add you should check your gear for rust. My tank wasn’t doing well and it turned out my gyre was rusting bad.

Great video so much info! 🐠 🤘

Great vid Travis

Thanks that was a lot of great information

Great video, very informative

Temperature change does not cause stn or rtn natural reefs constantly have a change of water temperature

Good video but I just had RTN and most corals except for a few lps are pretty much gone just after I figured out how to get my nitrate levels in check and corals growing here comes RTN.

No offense, Can you prove 0.5F can cause STN? (Edit: I love your channel, can hardly stand BRS channel now as it’s just subliminal advertising now). Just seems like few will be able to control that tightly

I’m not a water change guy with the system I run ( ati pro ) but over lockdown I did a couple of WC and sure enough I experienced STN 😭 i wish I never fragged and just left them alone ... fragging did work but I think it also would have been ok if I didn’t... interesting video thanks

Why would my monti go from doing great to a white spot in middle .... My hammers are ok my acan are good rbta are good mushrooms candycane all good some zoas shrinking ....i just added a aptasia eating file fish... Could that be it?? Alk was low calcium was high ...its a 34 gallon redsea I did 50 % waterchange

I’m about to start using a different salt. Should I do half of new and half of old for a couple water changes or just go for it? Or any variation of that?

Great video! I recently switched salts from Tropic Marin Pro to Brightwell Neo Marine because of availability. Ive had some STN in some of the more sensitive acropora. Would you suggest I switch back or ride it out?

Thank you for the video. I just lost big colony of Stylophora milka with STN. I think it was due to mysterious swing in KH..for years i had 8, now suddenly in one week it was 12…i dont know why,cause i havent changed anything… May i ask you what lights are you using over your tank and what setting? I have a Radion XR 15 G4 over 50 gal tank, but i can never achieve this clear white look with such colored corals. My corals are colored but i cant find any template or color settings to bring this colors out. Either its too blue,or too yelow/red…. Please help. Thank you🙏

Do you use UV in this tank?

Hi Travis, I have a question about dosing Alkalinity. I am using natural sea water in my mixed reef tank and this has a DKH of 7. All the videos I watch and people I speak to tell me it should be between 8 and 10 DKH. I don't know why they recommend this as natural seawater is the home of coral!!! I have 50/50 sps and lps in the tank, and would like to optimise their growth. Do you recommend I raise the alkalinity and would I need to dose calcium at the same rate to maintain the tank balance? as you always say to dose both at the same time

So what was it 😆
