question about dictyota

[home_depot]

Hello I new here and have a qustion about dictyota about a month ago I took down my tank because I had a bad outbreak of bubble algea and dictyota I took all my rock out and soaked them in murinc acid to kill everything on it replaced all my sand .pretty much started over but I had taken out all my corals I had during this time,well now I am starting to notice the dictyota is stating to come back. and I want to get rid of it before it takes over again. This stuff spreads like wild fire. I was told that a foxface would eat the stuff and was wondering what everyones thougts were on this.
My tank is a 75 gallon I am using ro/di water,have a good skimmer 20gallon sump.
Thanks for your time

Your in for a huge fight with dictyota. Here's some info I looked up along time ago when I had an outbreak. Some fish species repeatedly take bites from this chemically-defended seaweed and then spit them out after realizing that Dictyota tastes bad. Thereby spreading throughout your system.
The picture below is an example of the extent to which Dictyota can overgrow other reef organisms. Here the green calcified alga Halimeda opuntia is highly epiphytized by this brown seaweed. When Dictyota grows on organisms like Halimeda, it slows their growth rate and has detrimental impacts on its metabolism.
I had many tangs in my system that left this stuff alone. I then purchased 15 emerald crabs which did eat the stuff but could not eat it fast enough. I ended up taking down the system and baking the rock to kill everything. This algae is devistating and is nearly impossible to get rid of.

I had this type of algae. You are right. It can be devastating. I finally bought a naso tang and within a few months, he/she ate it all. I am now supplementing food by growing my own macro algae.
