Default What is this algae and how to get rid of

Just started Zeo system one week ago.

1. Gross water volume of your complete system (incl. sump etc.)
280 us gallons - tank plus two sumps

2. Net water volume (incl. sump etc.)
Estimated 250 Gal

3. Are you using a CaCO2 reactor or other technique
Two part "Bi-ionic" Ca and Alk through Dosing pump
i use Vertex dosing pump include Alk 、Ca、Mg

4. Are you using a PO4 reactor (how long, how long ago, etc.)
Just stopped

5. Are you using Ozone
No

6. Are you using UV
No

7. What skimmer are you using (type, rated water volume)
Reef Life Support Systems DB10

8. What are your actual PO4 and NO3 levels
PO4 0.04 ppm ( hanna ) NO3 5-10 ppm( salifert )

9. What are your actual Ca, Alk and Mg levels
Ca 370, Alk 10.4, Mag 1370 (hanna & red sea )

10. What filtration method do you use (refugium, DSB, Miracle Mud, etc.)
live rock, with chato

11. Type of light ( on Watt, color temp, how old, etc.)
Radion Pro 12 hrs on 55% ramping though day un and down in intesnity - Coral Radiance Preset.

12. What corals do you keep
SPS and xynia (which I have to prune every second week)

13. Tissue color (light or dark)
see pic.


What is the algae that is growing on my rock? How does one get rid of it?
Very interesting is that day one, polyps opened up on this SPS day one of starting system last week.
In addition to standard package i am also dosing 10 ml a day of flatworm stop. I had a problem and now they seem to be under control.

Hi Keith



The algae look like green hair algae, have you had them before starting ZeoVit already ?

Please also post your complete dosing regimen and how much ZeoVit material you have running at which flow in your reactor.

Have you already removed all the PO4 absorber you have used before ?

The systems KH is to high, would recommend to slowly decrease it to ~ 7 - 7.5 keeping it as stabile as possible there.

I was just going to run out my ph reactor then stop. Right now I have a little GFO mixed with some PH4x4 . The dosage I have been using is 2 ml Zeo start and 10 ml flatworm stop every day. 10 drops Zeo Bac and Zeo Food every second and 3 re day.
I did have the hair algae before I started Zeo system but it seems more pronounced now.
I know Alk is high now and have been bringing it down.
Should I run new GFO?
Also did a DYI reactor that does not work for shaking. Am replacing with a vibe as soon as glue cures and on part comes in.
Thank you G!

You need to deep clean. Its likely your tank has been running for some time now. Enough to get dirty enough where the algae is out competing the bacteria in the tank.
I would get some h202 from the dollar store and a spray bottle get some fresh salt water spray the rocks down and then shake them in a bucket of tank water then syhon out the bottom sand and replace with new water.
Your tank is no longer ULNS and zeovit will not compensate I've been there my tank got really bad too

Hello Keith, first thing I would recommend is to stop dosing ZeoFood, also replace the reactor as soon as possible.

In the meantime you can try to manually remove the algae with a brush regular even if it is a lot of work with your tank size. Adding some sea urchins:

Tripneustes gratilla
Mespilia globulus

Should support this process.

You can additional dose 10 ml Coral Snow once daily for some time.

Do you treat flatworms at the moment ?

Would also be interesting to know if the PO4 level has increased since you have removed the PO4 absorber.

Default Phosphate now 0.00

I was going to stop the phosphate remover, but instead I just upped it. Now with GFO I added a good bit of Rowa Phos. Phosphates have gone to 0.00. I am making water for a water change and going to siphon out as much of the hair algae as I can. I realize this will be an ongoing process.
Do you think I have to take out all the live rock, or now that my phosphates are at 0.00? That would be very difficult for me to do.
Although the flatworms appear to have abated, I have still been dosing FlatwormStop by Zeo - 10 ml day. Should I keep this up? I am not totally sure if they are all eradicated or not.
Should I feed corals now? I give them Reef Roids once in a while.
Bugger, thank you for your suggestions. Thank you G. I really appreciate both of you!
I will order the Coral Snow.

Should not be necessary to take the rocks out, it will just cause a big impact to the biology. Maybe replacing some pieces of the rocks with good quality live rock step by step is supporting the process also.

Your corals should not need additional food at the moment, which kind of Flatworms are you treating ?

Default Type of Flatworms

The type of flatworms that I have/had are Acropora eating flatworms.

That is good news for the rock. I will leave them in.

Than I would recommend to continue dosing it.

Default phosphates creeping back up

I am ordering more phosphate reducer as my phosphates are now at 0.06.
Let me know if you have any thoughts on phosphate removers.
I got the Coral Snow and have been dosing that 10ml a day.

PO4 absorber in conjunction with ZeoVit does usually not work very well as a quick decrease of PO4 can cause TN starting from the tips. If you like to do you can give it a try but use just a small quantity and increase it in small steps just to stop the increase of PO4.

OK, I will be cautious of my phosphates. What range is good for phosphates with the Zeovit system?

In a stabile ZeoVit system PO4 level within the range of 0.00 – 0.02 mg works really well.
