Purple slime on my sand?

I have a strange purple slime growing on the surface of my live sand. I have tried to remove it but it breaks apart and gets mixed into the sand and just makes a mess - what is it? How do I get rid of it?

Sounds like the same problem I had a few months ago. It was cyanobacteria. I syphoned it off my sand with a small tube held about 1/2 to 1" from the sand. I did this every few days when it would start to bloom again. After about 1 or 2 weeks it looked dramatically better. Check your phosphate level. I had high phoshates when mine bloomed. For several days I tested everything. I found that my fill water didn't have phosphates but after mixing it with salt it did. I thought it was the salt but after one more test I realized it was the dechlorinator. I changed dechlorinators and now my phosphate level is getting lower every time I do a water change.

This thread might be of some help. Algae Problem

I just went thru this about a month ago, I did a good water change syphoned all I could of the sand and turned the lights out for a few days. Someone had told me to dose some kalk will help to kill it off, and it seemed to work. JMHO

Thanks for the help

-I do use tap water- I will try siphoning it off the sand and dosing with Kalkwasser. I think my phosphates are high, I tend to get alot of algae blooms on the glass that is very difficult to scrape off. I have tried different phosphate buffers/sponges but nothing seems to work-

I think the best investment you could make is to buy a RO/DI system.
Something else that is better than nothing would be a Tap water filter but is only good for about 100 gals of pure water.

If you stop feeding it it will stop growing. A rodi system will help. Syphoning it off will help. Kalk will precip. phos but may cause other problems (high ph). You have to look at the big picture, its not going to be just one thing with a quick simple cure.

Water, salt, chemicals (dechlor), fish food all play a part.

Hi eel and welcome to Reef Frontiers. Alot of salt mixes contain Phosphates that is probibly why you are experenceing some on the new SW batches. As mentioned above most of the time P comes into the tank via input and food is the main one. What are you feeding your tank??

On a side note the use of kalk will cause Phosphates to bind with calcium and come out of solution as a solid (good thing) but with in 24 hours bacteria will once again disolve the solid and free up the Phosphate once more (bad thing)

take care

Thanks again

I changed my salt to the red sea brand the last time I did a water change about 2 weeks ago and the red/purple slime has been there since, I had never seen it before. As far as food goes, I have been consistently feeding my fish Ocean Blend for 6 months- It is a frozen food I buy from a guy here in Coeur d alene - I think he makes it.

oops

Sorry-
I get my food at Inland Ocean. It is in Hayden Lake just north of the corner of Government and Hayden ave. I bought the salt at Oceanview? It just opened in Spokane- kind of downtown on second street I think, I was checking out the store and needed some salt. I really think the change of salt had to do with the cynobacteria, I haven't changed anything else and the slime showed up right after I did my water change with the new salt.

I usually buy my fish at Inland Ocean and my corals at Aquatic Dreams.
