What type of substrate do you use?

  • Since with saltwater, substrate matters highly when it comes to keeping those living inside the tank happy - what substrate do you tend to use?

    I tend to stick with fine grained mediums that are around 0.5-1.7mm in grain size (mixed with some super crushed calcium) in order to allow for some sand shifting fish like my gobies to be able to dig (and be happy), while also having the benefit for the nitrate reduction done inside of the tank naturally.

  • I've mostly stuck with name brands when it comes to substrate for saltwater tanks (never really looked too deeply into which one to specifically use), along with making sure to use some live rock in order to provide the beneficial bacteria (although I always keep a lookout at night for any of the brittle worm since they are a pain in the butt for sure).
