400 Gallon Aquarium Restoration

We’ve recently completed a full restoration of a 400 gallon saltwater aquarium in New York.

First, we replaced old fluorescent lights with LEDs.

Then we pumped most of the water out of the tank.

After that, it was time to jump in the tank and remove live rock and catch all the fish.

The next day we pumped the remaining water out of the tank, removed sand and cleaned the inside of the tank. We let the tank dry completely for a couple of days and than we started the process of sanding the walls of the aquarium in order to remove all scratches. This was a very long process, as the tank had a lot of very old and deep scratches.

When all scratches have been removed, it was time to polish the tank.

The next step was to put new sand and live rock, which has been previously cleaned, in the tank.

After two weeks of hard work, the tank looked brand new!

Now it was time to fill up the tank with salt water and wait for it to clear up.

It took a few days for the water to get 100% clear.

After about 2-3 weeks of cycling the tank was ready for the starter fish. We added a small school of Monos followed by a pair of Squirrelfish.

A few weeks later we added another batch of fish – Passer Angelfish, Picasso Triggerfish, Tomato Clownfish and some more Squirrelfish.

Our full restoration project has finally come to an end. This was the biggest project we’ve ever done and we couldn’t have been any happier with the final result – brand new looking and very healthy aquarium!
