-Make sure u have 20 gal water mixed
-Break it down into buckets keep fish and inverts in a bucket with no live rock (so they don't get pinched or scraped)
-Liverock in bucket with tank water
-Save at least 20gal water
-if you are going to save the sand u may want to rinse it out if not discard
-set up liverock in tank ( don't set up all right away just the pieces in the bottom, u want them on the glass so they ate good and sturdy).
- rinse new or old sand or whatever substrate u use
-Put sand in bottom of tank
-now you can add water slowly (the pour it in on the rocks do disturb the sand as little as possible, makes it easier to see the tank a bit while aquascaping)
- while filling you can add the rest of your rock
- set coral in where you want it
- make sure tank temp is within1 degree of fishes water temp and then let them back in the tank
Start to finish should take a few hours. It is normal for water to be cloudy at first , it should settle down within a day
