Hi Everyone, just Starting Out:)

Your calcium level should be between 380 and 450, so do not add anymore until the levels come down. Check the levels before you add things. Also check your alkalinity. It goes hand in hand with calcium. Save up for a refractometer to check the salinity, it is way more accurate than a hydrometer and is one of the basic instruments one should have. Sometimes you can pick one up for about 25$ from someone getting out of the hobbly.
