I had brown diatoms for years in my cold freshwater tank chez, it was a real pain so I can understand how annoying it must be for you.

You probably know all the causes and possible cures for it, but I found this article that may be useful for you.

Hope you manage to get it sorted.

right this could be a couple of things other than diatoms

does it have a red tinge to it and does it produce bubbles ? if it does then this is cyno bactria very similar to diatoms

diatoms tends to disipate after a while and tends to be the above as diatoms have a very simple food which once used it is wiped out in a marine tank

if it is cyno then their are 3 things that cause it

excess nutrients
light spectrum
depleted flow

right best thing i can say to get rid of either of these will be an addition to the tank of a conch snail these are very good sand sifters and eat both diatom and cyno as well as some other but not all types of algea

when was the tubes changed and i know you have a little fight with phos (this will take a little while to get shot of) what is the full volume and what is the lph of all the pumps in the tank ?

Thanks guys

I Have had nothing but trouble with diatoms since buying this tank.
its never been without them.
I Bought the best Liverock fugie.........
it holds 94ltr
it has a powerhead
2 inlets that is fitted with the tank
and now I Bought a wave maker thing to break the water at the top
so I Can use one of the inside filters to send movement down.
I Feed very small amount of food in a morning
and a very small bit of fresh mussle flesh at tea time,which they eat up right away.......

I Have the lights on blue at 9am for about a hour
then I Put the Daylight on turn blues off.
then about a hour after I Put the other light on,sunlight
these are on around 6 hrs then I turn off sun about half a hour after put on blues
and turn off daylight......
I do a small half a bucket water change everyweek just to keep it right.
salt is about 24-25,check regular..
if it gets to 28 I Change a bucket and put r.o in to bring it back down...

I Need some more R.O Water now so will get some Saturday
and get the L.F.S To check phosphates again for me....

I Have raked about in the gravel to get rid of the brown..still looks a mess..
I feel like getting Everything out again cleaning tank and starting again.

maybe I Need more Live rock? but I Don't want to go there
as touch wood I havan't any undesirables and don't wan't none.
you know what I Mean don't you....lol
when these have gone there gone...............

heres some pics Karl I Have just taken......and Thanks for your help.

Well, being the marine expert I am ( ) the suggestion to get a conch snail sounds like it may be an interesting and useful addition to your tank chez.

Its a shame about the algae because the tank looks great otherwise and the corals all look as if they are thriving.

been having a think

you need at least 2350lph in the tank flow wise

do you know when the tubes were last changed in the hood ? as it is reccomended very 6-9mths

conchs do eat all types of algeas
sea hare only eats green hair algea
some crabs eat cirtain types of algeas
haloween urchin will eat most algeas
also for the sand look at some burrowing critters or fish as these will keep the sand turned over and diatoms at bay

other than the algea the tank looks healthy, you will always get growth on the glass front and back but their is a way to get rid of it slowly and that is raise the mag to 1500ppm over a very slow 2 week period and keep it at that level most algea's cant grow with this ammount mag

Thanks Diane for your Expert Advice..

Thanks Karl
The Lights have been in there since I bought the tank New from L.F.S
But I Have always had this problem.

I Really didn't want to interduce anything else in the tanks
as I Said when there gone there gone. but can't see a conchs being a problem.

The lights are fitted in the Lid and what I Can see I Dont think the back
gets much light... as you can see the lights are only in the middle.

Oh chez, you really are welcome. I am always willing to pass on my vast knowledge in marine fishkeeping.

right the reason i asked was i was going to sujest you pick up a little bit of cheato or calpera for the rear section but if the rear dont get much light not alot of point in it unless you want to add a light lol this will fight the other algeas for nutrients and win lol only needs to be a 6500k bulb nothing special standard 2700k energy saver is suitable.

sorry i am making you get things for the tank you dont want to keep but i think if you got rid of the algea's you will find you have a different veiw on it lol

shame i am not a little closer would pop round and give you a hand
