I have the same light but longer ,and kept softies and lps ,problem is it has no timer and you can not mix the colours ,whites/blues or both that's it .I have replaced it with a marine orbit, looks the same but has a timer and you can mix the colours and duration ,much better light for those reasons .

Ok. I've had this light for 2 years now and am struggling to keep some soft corals and am pretty much exhausted all my options on what the problem is. Yea it is a pain so i have put the light on a timer and have a blue led light that comes on before the main does so it doesn't shock the tank straight into daylight and the same for turning off bud didn't know if the light was to much or to little for certain corals

Thanks:

Do you feed your corals ,may be worth a try I add 2ml of marine snow every day  and my corals do really well more the lps than softies . (I also don't skim).As far as I'm aware your light should be fine for softies and lps ,maybe your water is to clean and all the organics are being removed .

There is no way that light can be to much for any coral being only 25w my corals get blasted with 320w of lighting I would say if you having issues then it's not enough light as 25w is not much at all and not enough for LPS to thrive.

You will always have organics in the water as in fish poo unless you have a skimmer that is massively oversized but even some will remain.

I'm now under the conclusion that fish poo is enough on its own to feed the corals so at present I'm not adding any additional food and seeing how things go.

Adding liquid food and not skimming is not ideal as you can end up saturated with organics and in turn bad water quality.

The maxspec units I run are 10000 LM + so the 1000 yours are putting out is 1/10th

25000K is the temp just means they more blue then white.

In my opinion the issue with the corals is the lighting.

I really don't see a problem tank looks real nice ,a marine spec in a large fish shop runs the same lights as you and his reef tanks does very well. Problem is with the more powerful lights they  need to be suspended and imo ruins the look of tank plus you will be burning more electricity  :lol:

You talking about my toadstool?  That's one of the problem ones. When I got him he was AMAZING but after 2 weeks he just went like in the picture and has been ever since same with all zoa's and yellow polyps after a few weeks they all end up closing up 😩

That starfish is also looking for food sadly a tank that size cannot support it that's hungry.

For corals of any type to not do well there is things you have to look at.

Lighting
Water quality
Maturity of tank
Water flow
Nasty hitchikers

There is clearly an issue if corals are clamping and the Duncan has dropped it's colour.

Yes an LFS may have them lights over a tank but how long does that stock actually sit under them before they are bought so you can't really compare that to a tank that has a coral living in it permanently.

You can set up a new tank and buy a mega looking SPS for example yeah may look great for a week but if the water and everything around it is not right you either end up with a bleached , browned out or a skeleton and in some cases this can happen within hours.

The OP has said they looked amazing at the start and all have deteriorated which clearly shows there is an issue in the OP's system.

With regards to electric costs that's all part of keeping a reef tank correctly

I'm not in any way putting your system down so don't think I am I'm trying to offer advice and help you have a thriving tank as there is clearly something not right and my personal opinion is the lighting unless your water parameters are out.

What's your

Nitrate
Phosphate
Kh
Alk
Cal
Temp
Mag
Sg

I can't see anyone running a full reef on them SPS and LPS successfully they don't put out enough for those corals to thrive.

Not all lights need suspending mine don't and they don't spoil the look
