i don't know what is going on but...

i am really worry about this green spots every where. i think this is green coralline algae and it was purple before but now it is green and round spots all over should i worry or this is just a process of having mature tank b/c tank been running 5 mount already. also on sand redish algae appear all the time even i clean them up next day again it is keep coming to sand and to the glass. now green one on rocks but it is not hairy its just a spot. what should i do 8 hours my ligths on it was actually 10 hours before b/c i have clam and my calcium was little high 500. also temperature 82-84 last couple weeks. i did WC every week %15. so.. what should i do or wait? may be it is good sign of something? no matter what i need help guys.

 

actually phosphate is ok but no3 was 15ppm almost two months. should i remove BB and change the carbon?

 

Well, phosphates can read zero and still be adding waste to your system. It might be reading zero because it is there in small enough amounts so that the algae is using it up w/o allowing it to build up in the water column and be viewable in your test results.

But yes, change your carbon, and if you run regular carbon, switch to activated carbon or something like a polyfilter.

Temp is a bit high too, can you run a small fan along the surface of your sytem to cool it off a couple degrees? Or install a chiller?

 

i don't think i have phosphate water i use ro/di and it is kent marine just bought two months ago. what else could be the source?

 

Over feeding, light period too long, not enough circulation(dead spots) Luna

 

i would say get a picture, its the only way someone can really identify it.

 

8 hours is too long for lighting, i don't over feed, every other day i feed them together with corals (zoo plankton) and brine shrimp for fish what else could be? dead spot that might be issue for RSM b/c BB and carbon area is the end of circulation. so i guess i have to get rid of BB and change the carbon also add LR crumble instant of BB. hiiim, what u guys think? who has RSM.

 

the red stuff that is growing on the sandbed sounds to me like cyanobacteria. Since it is a bacteria and not a true algae although it is referred to as "red slime algae" cutting back the lighting cycle wont be enough to contain cyanobacteria. Increasing the flow, reducing the nutrients in the tank, and lowering the water temp will help rif the tank of cyanobacteria. As for the green algae, is is slimey or is it more calcerous/encrusting?

 

green spot i think it is green version of coralline algae small like penny size or smaller spots.
