[ckramer215]

Two weeks ago i cleaned this up and now its back again in the same spot. Does everyone know whats growing in my tank? Its only around this one coral.

RED Slime...

 

[ckramer215]

Thanks do you know what can be the cause?

 

[pkane11384]

Cyanobacteria. How often are you feeding? What are your nitrate levels? How long is your photoperiod? What kind of flow do you have?

 

[ckramer215]

I am running two 240gph power heads. I feed the corals every 2 to 3 days. 20 percent water change every week

 

[pkane11384]

What size tank is it?

 

[ckramer215]

20 gal long

 

[pkane11384]

You may need to shift the direction your powerheads are flowing. Generally it grows where there is a dead spot in the tank

The other question you should ask is why is that coral so white!!!

 

[ckramer215]

Yes i will move the power heads around and see if that helps

To give yourself a better chance of getting rid of it. Turn of the pumps and take out a few teaspoons full of the sand where the slime is. Put it in a cup and rinse it till all red is gone. You will be surprised by how much is in there.

Also are you running carbon and some type of GFO. What are your Nitrate and Phosphate levels?

 

[ckramer215]

Its was 3 teaspoons of sand. The sand was hard, packed together. All gone, hope it stays that way.

 

[ckramer215]

Yes i am running carbon, Nitrate are close to 0. Phosphat not sure, i will have to check them tomorrow
