7/18/19 - Found my tank leaking from the sides. Had a bad feeling so I moved the sand and found a small crack on the bottom of the glass. Make sure you save your receipt! Innovative Marine was very understanding and worked with me to get another tank!
8/10/19 - The wait for my new tank gave me time to set up my dry rock! I used “Reef Welder” which worked great outside of water but hardens quick in water so you want to use this stuff before you put it in your tank!
My first two tanks were IM. My hopefully soon, frag tank is a IM lagoon 25. They were great when I had a problem with my first tank. Glad you found the leak
Other changes were on 8/26 - I changed from a fine sand to live sand since the fine sand was getting blown around too much. 9/14 I added green star polyps and 9/21 added purple star polyps. Everything was going good!
I immediately went out and bought Ruby Reef Rally and Kick Ich to medicate the tank. After a few days my blue chromis and two clowns were doing fine but decided to put them in a quarantine tank with copper anyways. On 1/13 the black clown died when I got home. I changed the water on the quarantine tank but the blue chromis died later that day. Finally, 1/14 the orange clown died.
Woah! Sorry your tank crashed. It's gonna take a while for the Ich to starve off in your DT. I would give it about 90 days to be sure this doesn't repeat. Keep your fish in QT at least 76 days. Ich has a 28 day life cycle but it can hide inside the gills. Give the fish 76 days of QT - but be sure to starve off that DT. If you put copper in your DT its gonna hurt your live rock. Copper absorbes into the silicone and forever more leaches out in trace amounts... Enough to kill corals.
Keep that QT tank going and dosed with copper. I would also treat for internal parasites which may not be self evident with Prazipro once the Ich is cleared. Those white cysts will fall off but the Ich has a free swimming stage - it will reinfect in the gills first. So, it looks like it's gone but its not.
Keep that fish QT as just a fish QT forever and never use it for corals because of the copper leeching.
Set up a separate QT for corals.
When you get a new fish, give it a 10-15 second rinse in fresh RODI, no salt to remove hitchhikers before adding to your QT.
Dip corals in Coral Rx and remove the base with a little living tissue with a dremil or a frag saw and reglue to a new frag rock before additing it to your coral QT.
Don't let anything wet go between any tanks.
Use a separate fish net for the fish QT. Be sure to wash, disinfect, and dry your hands well before going between tanks.
QT your new fish and corals for 76 days to make sure it doesnt happen again. Your pets and your wallet deserve at least that much.
I'm very sorry you had some losses. It happens. It's a learning curve. Just start quarantine from now on - and make sure your DT is safe before reintroducing any livestock.
Good luck,man, and best wishes on your next attempt.
