Getting Rid of Cyanobacteria

Cyano bacteria is a type of algae that blankets the sand and rockwork in our tanks.  It's an eye sore and people object to its presence in our systems.  You have a few products to help combat it, and then there is the non-chemical approach as well (explained in the article linked below).

RedCyano Rx (by Blue Life USA) works well. 

Getting Rid of Green Hair Algae

Green Hair Algae (abbreviated as GHA for this article) - Derbesia - is a form of algae that looks like its name. It is usually dark green, grows quite long if left unattended and spreads across your tank rapidly. Once this problem has begun, it can get out of hand in a matter of weeks. And soon you start to look at your tank in disgust, thinking “Why me? What did I do to deserve this plague?”

A number of things may have contributed to it getting a foothold in your system. Your nitrates might be too high, your phosphates may be too high (.03 or less is the goal), your lighting has recently been replaced or perhaps your bulbs are so old that the spectrum of light has shifted, fueling algae growth.

First things first. You need to get your water parameters to Natural Sea Water levels:

How to rinse out an older sand bed, and why...

If it is time to move from one tank to another one, or you are simply moving the tank from one location to another, the big question that comes up often is "how do I transfer the sandbed?" The reason this is a concern is because the sand bed traps all kinds of detritus and this builds up to toxic levels. While scooping it out of the tank for the move or the upgrade to a larger tank, these toxic zones can cause a major catastrophe when setting up the tank anew. And a sandbed loaded with detritus will surely feed nuisance algae.  Yet another reason to do this.
