Red slime algae

[Ajdecker74]

I am getting red slime algae. Tried cutting back the lighting. Anyone already been through this? I couldn't imagine

You have some serious nutrient issues.

You have some serious nutrient issues.

#Understatement. what are your nitrate and phos levels at?

 

[Danny Venditti]

and you definitely need some more flow

 

[Ajdecker74]

Just added a powerhead. Had return pump fail about 2 months ago and lost a couple fish

 

[Ajdecker74]

Didn't have this problem before I purchased new light.

 

[Danny Venditti]

it happens. lets start with basics
size of tank?
parameter levels?
equipment including the powerhead?

 

[Danny Venditti]

I would say test everything especially nitrate and phosphate and go from there.

110 gallon, 30 gallon sump, current dc flow return pump.ultra violet uvula sterilizer, diy algae scrubber, in sump skimmer. Temp. 78.4 salinity 1.026. Haven't tested other parameters in a bit. About 7.8 ph

Dosing anything? If dosing anything with amino acids in it, stop or decrease the dosage.

yes agree with rkpetersen and check phos and nitrate. if elevated reduce feeding and keep salinity as is reducing light will help a bit but might want to consider a reactor with phosban worked wonders for me.

reduce to 6 hours day no need for any more than that really you can have blues on longer but keep the whites down.

 

[Danny Venditti]

also with a 110 you may need more than one circulation pump to avoid dead spots that's probably what is causing it to form on the bottom. increase flow and do a water change and suck out as much as you can.

Is that an led fixture? Ou'd so, what are your setting?

Cool will try that. Been changing water and sucking as much out as possible. Thanks for your time

80% whites 100% blues. 9 hrs daytime. 20% blue 5 hrs moonlight

 

[Ajdecker74]

Phosphate is definitely high over 5

no problem I will venture to guess it is a phosphate issue combined with flow. we all deal with it. you are not a reefer till you've had red slime!!!!!

I would turn the whites down to about 30-40% that should help. Maybe the blues down to about 70-80%.
