GFO and dirty glass!!

[lou dog420]

I have noticed over the past few months that when I don't run any GFO, my glass stays clean, only having to clean it maybe once a week. When I run GFO, I have to clean the the glass like every other day. Has anyone else ever noticed this??

That's a new one for me. Maybe the #reefsquad can help.

New to me as well. My experience is actually the opposite. Glass cleaning frequency is an indicator my GFO has exhausted itself.

I believe I’ve experienced the opposite; that fresh GFO results in cleaner glass.

Odd.

Tagging along.

Interesting

Couple of questions. Are you rinsing your GFO prior to installation in your system? In what manner are you using the GFO? If it's in a reactor, it may be your flow is too high in the reactor and the GFO is tumbling too much, thus breaking down. I have experienced that when I first started using the stuff.

Possible the GFO is adding iron to the system which the algae was lacking in it's absence?

I run it in a BRS rreactor,mixed with carbon. It is rinsed very well, 5 gallons run through it before it goes into service.

What color is the stuff on the glass?

I never considered that, you may be on to something! !

Brown

Brown

Weird.
One would suspect diatoms or rust.

Im pretty sure its not diatoms.

What are you phosphates and nitrate reading and what kind of light are you running? How long are you running the white spectrum?

What are you phosphates and nitrate reading and what kind of light are you running? How long are you running the white spectrum?

Nitrate 1.5, phosphates.. 01 to .05.
2 kessil 360s, 100% intensity, 60% spectrum, with 2, 54 watt T5s, coral+ and blue+.
LEDs run 8 hours at full intensity with a 3 hour ramp on each end, T5s on for 10 hrs.

 

[jsker]

Nitrates should be between 3 and 5 or slightly higher. Phosphates .02 to.03.

I would recommend running your white spectrum for a total of 5 hours to 5.5 hours including ramp up. I found after backing off my whites my glass stays much cleaner algae is almost non existent and the corals are still growing nicely. I clean my glass about every 4 to 5 days

In my experience (since i'm a professional at growing dinoflagellates /joke(but not really) ;Hilarious) it is most likely a non predatory dino. I've scraped the brown stuff and look under a microscope and found tiny dinos about 1/50th the size of the more invasive and toxic dinos. I will imply that adding GFO reduces nutrients to allow the wrong competitors. So, really the only solution is to not run GFO.

Was there a reason for the GFO?

What ratio of carbon to GFO do you use in your reactor? Is it packed tight or is it tumbling at all?

2 to 1 carbon and GFO, packed, sponges on both sides, no tumbling.

No, no reason for the GFO, I just enjoy spending my money on it!! Offcourse there is a reason!!! Lol
