Hi guys, I’m selling my blue tang and yellow tang which has been with me for slightly more than a year. They are fat and healthy. Blue tang is about 4.5inches and yellow tang 4inches. Both are feeding on pellets and any frozen food. Prefer to sell them together, @$120. Collection in the east.

And this is what happens when it is too high – burnt tips.

Something I like to share on reef keeping. I read from somewhere and find it useful. There is a correlation between alkalinity, light, and nutrients Most corals – particularly acropora and SPS corals – contain photosynthetic algae, called zooxanthellae. It acts as a sunscreen and is what gives them their color.. Phosphates and nitrates – aka ‘nutrients’ – act as food for the zooxanthellae. To much food will mean too much zooxanthellae or ‘sunscreen’. Not enough food will mean not enough zooanthellae or sunscreen. If you have your alk in the 6 and 7 range, your nitrates and phosphates need to be low so you don’t stunt growth. Less than 0.03 ppm phosphates and 5 ppm nitrates would be a good . On the other hand, if you keep your alk in the 11-12 range, you need to keep your nitrates and phosphates much higher “Burnt tips” occurs because the zooxanthellae algae can’t keep up with the coral growth. Eventually if the zooxanthellae gets further and further away from the tips, they will die halting growth. Example of alkalinity at a level that is right on the edge of being too high in relation to nutrient levels
