Came down this morning and marine tank was crystal clear, fed fish. Went and checked other tanks came back and my marine tank was very cloudy, white cloud. This happened in 5 minutes,,?? Please help

Maybye try testing your ammonia and telling us the results, could be a possible ammonia spike wich could be fatal for your fish.

Ammonia test 0. Why would it do this in 5 minutes, water in sump clear???

How long has the tank been set up? Was it cycled properly? It is most likely caused by overfeeding or poor tank maintenance. A water change may be advised.

Been set up for 9 months, water and filters changed weekly.
It seems to be clearing now slightly, been about 1 hour???

Did you read the linked info in my post?

Would macro algae cause this, its growing on the back, it looks a bit milky

I agree with @Fishmanic , are your fish eating all the food your feeding them?

Solved problems, my macro had gone sexual and died apparently, and released spawns into the water. The tank is now crystal again

Sudden cloudiness in a marine tank can be due to a number of things...
- bacterial bloom (won't necessarily see a chemical spike)
- phytoplankton bloom (often looks cloudy before going green if it isn't killed off or consumed by filter-feeders)
- macroalgae releasing spores (look for macro that appears "empty" or hollow - that's what released stuff)
- something spawned (most common in smaller tanks; unnoticable in large ones)
- an Enchinoderm died (they can disintegrate rapidly)

As far as the macroalgae releasing spores, some varieties are worse for that than others. It can also be triggered by swings in temperature/salinity, changes in photoperiod, or repeated physical damage such as from large snails chewing on the stems.
