I don’t know what else to do!

[5star]

My innovative marine 10 has been set up for almost 2 years now, I never had a bad algae problem.. until recently

about 2 months ago I added an AI prime 16 hd. Using David saxby’s schedule (lowered intensity), it was fine for a few weeks.

ive had a horrible outbreak of this brown/green algae, my water is disgusting!
I’ve tried everything, 40% water changes twice a week, replacing filter pads daily, turning off the light for 48 hours, and just recently added a uv sterilizer.
I don’t know what else to do

you might want to dim down the whites reds and greens on that program. those colors specifically help algae grow

Wow that's pretty bad. Sure everything else is in line?
Nothing else has changed?

 

[5star]

. Only thing that changed was addition of a few torch corals and a new light

 

[Dave Bayliss]

what are your parameters? phos, nitrate etc?

looks like a bacterial bloom

 

[00W]

Do you still have the old light?

 

[5star]

Yes I still have the old light. Phos is around .05 fluctuations from .03-.05.

 

[PeterC99]

which UV light Are you using?

 

[00W]

I agree. Bacterial blooms can happen when you ramp up the lighting. I've been there.

 

[5star]

Currently using ai prime 16

 

[Tamberav]

What UV sterilizer? and how long has it been on? Because a UV should be able to handle that...unless its malfunctioning or underpowered?

 

[Dave Bayliss]

Yes I still have the old light. Phos is around .05 fluctuations from .03-.05.

what about your nitrate? are you dosing anything?

 

[5star]

I’ve had the sterilizer in for 48 hours

 

[5star]

Did a 30% water change, sterilizer is still plugged in, looks a bit better!

 

[5star]

~72 hours with uv sterilizer

I agree, looks like a bacteria bloom. I would cut the lights for a day and give your u.v. a chance to get ahead of it.

 

[Lovelydrew]

I was going to say the exact thing. I would definitely cut the lights off for 1 day. You'll see a huge difference the next day, and it really doesn't have a huge impact on your livestock.
