Nuke the hole tank and start over?

[klavmaister]

all the corals died within 24-48 hours. And i men Thorsen of $ in stony corals. The aquarium is 14 months old, everything was going well (almost) then almost all the corals died and some of the fish were not in top shape. On holiday now and coming home in 5 days to an aquarium where everything is dead or something is alive. considering starting over. Have probably thousands of vermetid snails, have some bubble algae, and have had abtasia. Recently I got cyano bacteria, and when I got rid of them, I think I got poisonous dinoalgae, that sent the aquarium straight into the bucket

reboot? how should i do it? RED sea reefer 250 g2

You can restart from scratch but unless you fully understand where your mistakes were made and learn from them or you are destined to repeat the same outcome.

Unless you find out where things got derailed, it will always continue to get derailed.
So its best to figure out where something went wrong and why something died.

Do you know your basic values for your tank?
Like the Salinty, Ammonia, nitrate, Phosphate, Ca, Alk, Mg?

This might help you figure out why you have cyano, and why it went though a crash.

Got ICH/vaulted in the aquarium twice, ran without fish in the aquarium for about 120 days. got 0-0 nitrate and phosphate. (think therefore) when cyano died then dino came. why everything died, I'm not sure, have a longer thread here :
