Brown Sand

    My sand has started turning brown in areas. Is this a problem, or natural?

    How new is your tank?

    Welcome to Fishlore.

    A dirt brown color sounds like it may be diatoms, a common form of algae. It will go away on its own, eventually.

    Hi sek1958 - sounds like brown diatoms possibly from the water used to fill the tank. Normally see that when not using RO/DI water. No protein skimmer will make algae control problems harder. Yellow tangs get too big for a 29 gallon and they need a lot of swimming space.

    What size tank do you recomend for the Tangs? 50 gal? I did install a protein skimmer and I clean it out daily.

    Thank you for your help.

    The often accepted bare minimum for a Tang is 3 foot tank x 1.5 foot wide, and 1.5ft high - or 50+ gallons. The FL profile states 55G as a minimum.

    Preferably, most would suggest 4x2x2, or around 115G. Tangs are very active and like to 'stretch their fins'. the longer the tank, the better. :)

    And yes - the brownish colouring is most likely diatoms, and will disappear on its own as the tank matures along with good husbandry (water changes).

    Ahh but depends on the species and what goes in with them!! This has alot to do with size. Not all tangs grow the same size some grow very large and others grow medium size and yes there are some that grow smaller in size. 50 would be the right size for those that grow in the smaller size. Study them and get the actual growth sizes you will see what I mean.
