If so, then I'm battling the same thing myself. My rocks are red/green and develop bubbles all over them. I thought it was the start of coraline algae at first. Boy, was I wrong. I do have a rock with a tiny bit of coraline that I'm trying to see spread. It's something like my last bastion of hope.
How long can I leave the lights off for to combat the dinoflagellates without adversely impacting the coraline algae?
I hope these related questions don't amount to a hijack of your thread. If you feel they do, you're welcome to move this post to its own thread.
take a pic a post it on a new thread or somewhere. dino's are like the pics bears posted earlier in this thread. what you may have could be red slime algae also.
so if it's red algae if it's alot scrub the excess off while syphoning the water to catch the particles rubbed off then use red slime remover by following the label and completing a water change after, then increase your water movement (this part i'm not 100% sure works but that's common knowledge as per articles i've read but personally i've had tanks with tons of water movement with red algae but i'd increase movement anyways to be sure)
If it's dinos, turn off lights for 3 days making sure tank stays dark (tank lit up in a bright room of indirect sunlight) after 3 day it should be all gone. if it's really bad you may have to do it again like in a week or so.
No matter what treatment or issue you had it will come back if you don't eliminate the source. Most likely it's the quality of the water you are using for topoff or SW changes.
To me, having a successful SW/reef tank you should start out with good quality water. Remember unlike FW tanks, SW tanks typically have strong lighting and not enough plants that will keep compete with algae to keep nutrients low. Algae LOVES strong lighting and nutrient rich water. We have minimal control of lighting if we are keeping photosynthetic corals because those animals depend on lighting to sustain life, so we MUST control the other variable. Corals that need light needs relatively little nutrient in the water to live because most depend on photosynthesis. The nonphotosynthetic corals need nutrient rich water but little light and to control algae in these tanks you use very little light (i have little experience/knowledge with these types of tanks)!
To control nutrient in a SW tank.
1. start with good quality water, feed just enough to keep animals healthy (this is where most people make mistakes by over feeding and create nutrient rich waters too)
2. Use a really good skimmer because it will remove waste before it breaks down causing havoc in your tank.
3. water change and vacuum sand when you do. I personally alternate and only vacuum half the tank at any time i'm doing water change so i dont destroy all my bacteria.
4. you can use ROWA phos remover or some type of GFO. Don't use the aluminum base as this has a negative effect on some corals over time.
5. use quality lighiting and control lighting schedule.
6. keep bioload at a reasonable level.
good luck and hope this helps!
