did the bubble algae that popped three days ago do all this?

After all that I forgot what i was posting about... :? came home from work and found that a bubble algae that had been on one of the live rocks had popped and the shell had traveled about 1 foot. I took it out and didn't think anything of it. now about 4 days later my water has this greenish haze and the live rock all seem to be greenish, the back wall down by the sand seems to have taken on that same disturbing glow as well. I scrubbed the walls all that i could reach anyway and I changed 25 gallons of the water last night and it looks a little lighter but maybe i'm deluding myself.

so what do u think-- one little bubble algae do all this or what??

ps- how can you tell if your rock is starting to go purple, doesn't it start green??
 
It sounds like your average algae bloom, I doubt it's conected to the bubble algae, but I suppose it could be.

How long do you leave your lights on?
How old is the tank?
What are the water parameters, specifically ammonia, nitrite, nitrate and phosphate?

You can usually clear up a freeflaoting algae bloom with a water clarifier (make sure to get one that is safe for SW), or a UV sterilizer, but either method is a bandaid fix, it does not address the underlying problem.
 
here are my test results

nitrite 0
ammonia 0-.25ppm
nitrate 0-5ppm
Ph- 8.3
Salinity- 1.023
Nitrate 5
Calcium- 450-500
phosphate- .2

i had 40 watt daylight (which i turned so it's off now) and 40 watt actinic
they were on about 12 hours except the couple times i fell asleep before turning them off

i added some phos-x to the sump

i also purchased a large sprig of red caulerpa, and a few cerith and bumblebee snails

do you think i should scrape coraline into the powerhead stream?

or add molybdenum and strontium?

or add iron?

these will spur the coralline, but will they also spur the microalgae?

any help is greatly appreciated
