as you can see in my pic I have a thick covering of hair algae. BUT its really only in half my tank. does anyone know why this is....

Algae is just like corals. They have their preferences too (flow and lighting). However, eventually, you tank will be covered with that unless something significantly different is done on your tank to stop them. The GHA guys are very efficient with using resources....
 
I want this challenge in our challenge thread below in this forum if typical ways don't work to remove the algae

if the usual nutrient controls don't pan out, holler!
 
same lighting on both sides of tank have a led light in front and a 2 bulb t-5 in the back. the hair took off on the right side of the tank and is very very slowly making its way to the left side.
 
I would visually rate that system at 2 - 3 years old is that correct

it's not that nutrients are strongly tied to low-level algae growth, its popular online to claim so, but doesn't really pan out in gigantic algae correction threads. your sand bed has some minor accumulations in it, no worse than mine, no grazers matched for your invader, a few years maturation in this condition, and you have low level algae growth.

there is specific work you can do to make this go away in about a week and not come back per 500 examples in our thread.

it is also an option to try and handle the algae only through the water and deal with the variables that will lend
 
excellent input. each tank has unique maturation rates, but this one takes on nutrients and stores them to a small amplified degree we can see. again my tank isn't pristinely clean but I had this level of deposition after a few years, it just means your input rates and export rates are a little different and the algae will be there to grab it.

try all other methods and right when you're ready to rack your brain and want this done in about 7 to 14 days consider the documentation we have posted
in the reef 2 reef algae challenge thread


there is a very strong factor to consider within your deep sand bed. any form of nutrient stripping you may employ to avoid having to take hands on action against the algae is working directly against the action of your sand bed, and the sand bed is working directly against the action of the nutrient stripper, making you press harder for stripping the nutrients putting corals at risk.

a true long-term adjustment requires redoing that sb and altering the export practices within the tank that make it accumulate. this is why I only do nano reefs too much work in large tanks


I know you don't want to do a big job like that nobody does, some lucky combinations of grazers or even GFO to initially shocked the water column could help with no great tank work. however within the next year or two the balance will not be the same as it initially is if we ignore what may be some cleaning work. I think it will colonize the other side given enough time

a specific and documented set of repeating actions can specifically arrest that algae growth and stop it permanently, the variability lies when you try to attack it only through the water.
