No matter what salt you are using, you will need test kits. Reef Crystals will provide more than Instant Ocean, which is what I'm guessing you use now. This will be especially true if you are doing weekly water changes. But, you will still want to monitor your tank parameters. IMO, you really don't have to check your water religously. A quick check up every few weeks would be fine or if something looks out of the ordinary. Some things you will want to check are:
-Nitrate
-pH
-Salinity
-Calcium
-Alkalinity
-Temperature (especially since it is summer and small tanks can heat up quickly)
