PS, this doesn't have anything to do with yor algae, but I would check for nitrAtes/phosphates from your sea water...

test results from water i use for pwc ( natural sea water ) :

nitrate - 0
nitrite - 0
ammonia -0
phosphate - 0.1

also checked tank salinity and is sitting at 1.025

so all is good there isn't it

phosphate - 0.1
This is a source where your hair algae could be coming from.
I was asking about the salinity in your tank. If the water evasporates and not the salt, if you are adding more SW, the salinity will rise.

But 0.1 is the lowest possible reading i have on the card that came with the test kit

and if the salinity were rising it would show on my hydrometer and like i said it's reading 1.025 which is exactly where the level indicator is on it
i have a glass one and it's all the one colour apart from where it shows a green section which is the reccomended salinity and the water sits right in the middle of the green section which is where the lfs told me it's suppose to be.

and as i said before my tank water has never evaporated at all so therefore salt levels wouldn't increase as the freshwater doesn't decrease right ?

Hmmm, I have a 20G with en Eclipse12 hood and even the water evaporates out of that, even though it is totally covered. My main concern was if you are adding only SW for top offs, eventually, even your hydrometer, will show higher readings. Hydrometers are not as accurate as Refractometer and you may not notice the change, for a long while.

unless where your aquarium lies there is 100% humidity, it evaporates--I promise. It may just not be enough to notice with a hydrometer, whereas a with a refractometer you would definately be able to tell.

And when I got hair algae I changed my bulbs and never had another problem with it. Apparently factory bulbs will go bad before a year's time--at least mine did. So just in case I try to change my bulbs every 6 to 8 months to be safe.

0.1 is the same thing as .10 Normally, tests show as low as .05 or less so I bet having phosphates at .10 is your problem.

card looks like this and where the black lines are is where my lfs told it me it was safe mine is the very first one if not lighter



is this right or is that showing me there is a phosphate problem i can't see where it's coming from if i only feed a very small amount every second night and only have 3 fish it's now down to 2 now i lost the chromis

It could be coming from your source water.
