I had this problem recently. I had a seam failure on my 75 gallon this past Christmas. Separately, I was building a new tank in my basement. So I had to rush and scramble, and incorrectly set up my 'new' tank with coral and fish far, far sooner than I was planning or expecting to. Because I rushed the process, I'm basically going through new tank cycling and ecological succession which is pummeling my few acros. It took about 6 weeks, but I eventually started loosing some. I've sadly lost 3 Acro's this month and two more are going through STN. Worse is my budget only supports small actions at a measured pace. I spent more than anticipated plumbing the new system in an emergency (rather than over time as planned), so I don't have funds to throw at trying to fix it. All I've been able to do is water changes. And because I went from a 75 gallon tank to 220 gallon tank prematurely, I didn't have the large water containers on hand for a big waterchange. Doing 20 gallon changes on a 220 is a drop in the bucket. So, I've slowly been acquiring large Brute trash cans. Watching corals die as I wait another week or two for more funds, to then wait for parts like float valves to ship, to finally change more water. And then I also had to move the RO unit, because it was across the house and up two flights of stairs where my 75 gallon tank was. So I had to fill the 220 with 5-gallon buckets until I was able to replumb and move the RO.... Everything has been a 3 months headache as I react. And it's all a follow-on to having to rush a plan I had due to a tank emergency. Rather than follow the plan I had to do it correctly. It's basically left me sad and discouraged as I watch my Acros wither each day. I know it will improve with time. This week I purchased my last 40 gallon can. More salt in in shipping. And the new 220 will stabilize. But, right now it feel like the last 5 years of effort went down the drain the day my 75 gallon tank failed. What I've been trying to do is focus on the win's. Like recognizing none of my fish were negatively impacted, my Magnificent anemone is still thriving, and some of my favorite corals like my birds nest and purple Stylaphora haven't seemed to notice a change and are thriving. But it's so hard to focus on the good when corals are wasting away in front of you.

Really appreciate this topic. Very unique, and needed to be spoken about. Thank you.

Thanks for this video Mark! I setup my first saltwater tank while deep in depression. It helped immensely! Wishing you all the best!!!

Thank you! I really needed to hear stuff on this topic!!

I have this problem as well.... I thought it was the Australian Summer heat. I had my tank up at 31 Deg C. picked up a chiller to fix that, but the sps still dying and stripping out. Parameters all in check, but Im sure that I have a magnet that has rusted up a little (frag rack covered in zoas). Time to remove that Magnet... Thanks for the motivation @melevsreef

Hey! So sorry to hear about what’s happening to your reef tanks. Something that has helped me with dinos is adding a lot of pods. I bought like 6 bottles of pods from reef nutrition and within two weeks the dinos was gone. Food for thought =)

Muriatic acid will etch glass, weaking its structural matrix. For the cleaning box idea

Hey Mark I had the same Dinos on my sand. I beat it by siphoning them off and then adding aquabiomics sand. It could be anecdotal but worth a shot. Also raise my nutrients but you said you did that. I'm sorry man stuffs a bummer.

I read an article that said the carbon supply got disrupted by Russia/Ukraine and places have been sourcing cheaper contaminated carbon with heavy metals

Sorry for your loss mate ❤❤❤

Going through exactly this. Just can't get a break. most corals fine a couple sick. Any new corals die within weeks. depressing. I will come out the other side tho.

A skimmer 100% aerates water. It does not oxygenate water. Big difference

I’m at the point after 4-5 years of reefs that my current one has had many deaths and I’m just not happy with it. Hoping it turns around.

❤❤❤

Ozone might help. Poly Filter.

My new Radion is making me depressed, it keeps turning itself on in the middle of the night

For me, the audio and video is still way out of synch

Way to long could not make it through
