So much to learn but this has been brilliant, thank all.

Update

Tested copper and 0
New amonia test 0

Re tested water to go in 1.026

Here's the kicker, I took the hint from a couple of posts on this thread. I havnt tested my water for salinity in tank as it didn't occur to me that what I was putting in wouldnt be the same reading. Everything I put jn has been good salinity readings so why wouldn't my tank be......

Easy answer because I top up with salt water not RO :(

Tested my tank and its sat at a lovely 1.50..... seriously such a school boy error I guess but I assume this is causing me all kind of issues?

I've done a big water change today 50%, tested half hour later and 1.040 so better but I guess this will take time, im ordering an RO unit as we speak should I remove a bit of water when I'm ready and top up with RO until the tank is stable?

Last kit to arrive is phosphate

Aha! Yep, that kind of salinity will indeed be a problem!

You are right to bring it down relatively gradually. 30-50% water changes over the next week (personal view only!)

Once you hit 1.025-1.026 then you are good! I think an auto top off system(ATO) is worth its weight i  gold as it takes away the hassle!

Wow,  1.050!

Normally you want to change salinity as slowly as possible but with it being that high im not sure. 

Let's see what @HK_Fuey  thinks ...

Ps if you've got some RO could just remove a litre from the tank and put a litre of RO back in its place,  save you mixing loads of new salt water (don't do big amounts like that at once)

Ouch 1.050

But it sounds like you now know what to fix
I would reduce it gradually. If you mark the water level when at the right salinity you can top up manually to that level every day with RO, although an ATO makes it so much easier. I have a little IKEA kitchen cabinet in same colour as tank cabinet next to my tank. I have a 25 L container in there and a cheap Kamoer ATO that pumps RO from the container into my sump when the level drops.

Change by around .02-.03 a day so you don't shock anything. Agree on the idea of taking out a scoop at a time. Could let the RO top up, but you'll have to keep refilling that. Watch pH too, as big changes can impact that too. Slowly slowly.

Hi all

Little update and follow up question, salinity is slowly coming down 1.036 after the initial drop it rose up and now I'm dropping is a couple of points a day with addition of RO.

The question is about my gsp which now looks more like an extension of my rock with probably algae on it. Is there a chance this survived or should I cut my losses and take it out, I've read about cleaning with a soft brush but not sure about that.

Cheers
Steve

Just give it time. It may sulk for a week, but may still be okay.

Absolutely agree with @marine_newbie - just give it time. It is absolutely amazing what comes back with a little time. I had a Goni which closed up for about 6 weeks  - nearly took it out several times but it suddenly woke up! It has done it a few times since - have decided it is just grumpy!

Looks like cyano maybe. I'd be tempted to hold it in front of a powered, close enough to blow the cyano/algae off. It's pretty durable stuff normally, so may well come back.

Yes it does look like cyano ,you can try to brush it off with a gentle paint brush ,or increase flow .
