Cyano after adding t5s

[mps026]

Hi all,

Just added two t5 coral plus bulbs adjacent to a photon v2 led and started seeing some cyano. Only had the t5s on for a few hours. Any suggestions?

I did cut the white light output on the leds in half when i had the t5s running.

Thanks!

Mike

@jason2459 Isn't this what you did?

Are the t5 bulbs new? If no how old? I just got rid of cyano in my tank by using blue life red cyano rx. You can check out my build thread if you want, I documented it.

You just added probably 2 to 400 par to the top of the tank.

 

[mps026]

Yes new bulbs, will check out ur thread ty

 

[mps026]

I will check my par levels tomo to see the diff

I just have spots of it on higher up rocks which i easily scrape off... should i treat? Or does it ever subside on its own?

yea It will go away. Itll burn off the nutrints its feeding off of and go away. Its kind of a bloom, from the new spectrum is all and prob intensity.

Not a dig at all,
This is prob why a lot of folks for years(even before led) have said "X light gave me cyano"

Kind of. I added two coral+ bulbs too my 3 fixture ocean revive setup initially and complemented those fixtures well.

Then I replaced the ocean revive fixtures with 4 reef breeder photon v2 fixtures with the T5s down the middle. The reef breeders have more control over the colors and the white is a very warm white that bleeds into the red spectrum a good amount and looks yellowish to me by itself.

I liked with those fixtures a blue+ and true actinic combo. The Coral plus has reds that I didn't need now and the new fixtures has its own red channel I can tweak out if I need it.

Either way Cyano wasn't an issue but my tank is well past its initial cycle and I'd say is starting to mature. My mark for that is a decade and it's getting closer.

I just added 2x 2 bulb T5 Blue+ fixtures to my Gen4 Pro set up and I'm having the same issue. Chalked it off to algae bloom from the new lights. Water parameters are spot on so i know it isn't nitrate or phosphate. I'm just syphoning and going small water changes as the tank acclimates.

I just used a little bit of hydrogen peroxide every other day for about a week

Will not hurt your coral and beneficial to your fish!! Check it out on YouTube

 

[mps026]

Thanks for all the suggestions. I am only keeping them on for a few hours while everything adjusts. How much hydrogen peroxide?

 

[marvo409]

Depends on tank size

 

[marvo409]

I have a 210 so I used @ a cup every other day!! It also lower nitrates and phosphates

 

[marvo409]

If u decide to try turn off main pump for about 30mins leave Powerheads on

 

[marvo409]

It's easy fast and very effective

Are you just dosing it straight in to the tank's water column?

 

[marvo409]

Directly into the tank

Results are almost instant
