Please help

Went on vacation for two weeks and came back to this. Need help figuring out exactly what it is and how to get rid of it.









Thanks for any feedback.

 

Cyanobacteria,thrives in low flow areas and in nutrient rich(nitrates and phosphates) environment.It could have been caused by overfeeding while you were away.The best way to fight it is with water changes to decrease nutrients,and increased flow.Siphon out as much as you can when doing a water change.You can also use a turkey baster to blow it off of the rockwork and other hard to reach places.

 

Ok. Thnx. I have 4 900 gph powerheads. 1 on each side and 2 on the back wall. Too much? Should I get a wave controller to control the powerheads? 125 gallon tank

 

+1 to cyano and siphoning off with water changes. Also looks like some detritus on the rocks - just turkey baste that off when doing a water change and siphon out. It's amazing how our tanks suffer when we go on vacation...

I'm thinking I should advertise house sitting for fish tanks as a way to make some extra money in the summer

 

You don't necessarily need a wave maker though they are nice to have for creating random flow.You can simply try to eliminate dead spots(no flow ) by redirecting the powerheads you now have,try moving them to different spots to see what would work best.Cyano can take some time and patience to get rid of,just thought I should let you know,it isn't going to go away quickly.Most tanks have at least a little bit of it in some areas,when conditions are good for it's growth it can spread quickly,it takes patience and persistance to get rid of it.

 

+1 to all the above. Great idea, OFK.

Not too much at all. That's only 28.8x-- Good for soft and LPS corals; most SPS species would need much more. Furthermore, not all powerheads play nice with wave controllers; the constant switching sends some to an early grave.

 

Ok. Cool. Thnx. She had them all pointed either straight out or upwards. I have the two side ones pointed more towards the sandbed. She didn't want them pointed down because it was blowing the sand around. Oh and on top of the powerheads I have a little giant pump coming off my sump returning water to the tank through a 5 ft long spray bar
