reef crashed

After a long winter of not taking good care of my reef tank, I started to do better this summer and now all of a sudden things died. Everything was fine after I added 3 SPS corals (montipora spondoges, chalice, and a green encrusting coral) which I added to lower my Calcium and Alkalinity levels...

I recently had a total crash in my IM 20...and I am not entirely sure why. Looking for possible answers as a learning point. The question is: what was most likely the cause for the rapid crash of what seemed like a very stable and happy tank. And given that things stabilized pretty quickly...

Dear all knowing R2R, it’s been a fun ride building this tank but today it seems something was way off, almost everything is dying - I’m curious what the major issue could be, all information I provide may or may not be relevant. Is it bacterial? Acros(dying): are turning a little light...

Recently, I had a alk swing from 11 to 30+ due to human error and wiped out all of my fish except for a pistol shrimp and some CUC as well as all but 2 of my corals The ATO is a 10g and can barely hold all of my coral, I run a Seachem tidal 55 on the 29g DS and need to keep it on the DS so it...

It pains me to write this but I lost 25% of my corals I was growing over the last 3 years in less then 2 months. The only person to blame is myself and that's the only way one can improve. Watching your coral die slowly is a painful site. What lead up to this and how can I prevent this in the...

Hi everyone. You may think what you’re about to read is crazy or a joke. Just hear me out and then let me know what you think. One week ago I added a starry blenny to my mixed reef (took me 3 months to find one locally). Main purpose was for him to eat some random GHA. Not a big issue, just...

Two weeks ago I made the worst mistake to date when it comes to my nano. I went to dose my iodine (Lugol's) and did 2 drops instead of one. Then I dose double the amount of trace elements. I had planned to do a 20% WC the following morning. It seemed to be too late. My zoas, green stars, lepto...

I'm looking for advice on how to tune my lighting setup, which I'll be finished putting together next week, and because I have bleached corals at the same time I'm looking for some help on how to configure things, so that I don't make things worse. A lot's gone on and I've had a hard time...

Hi everyone! We never think or at least we hope it will never happen to our own tank then bam it happens - the tank crashed! A crash is never expected and when it happens most of us panic... we scramble looking for information and help to save it. I know because it finally happened to me due to...
