Phytoplakton Bloom

[SDReefer]

Hi guys, the tank in my greenhouse has experienced a huge phytoplankton bloom in addition to my green hair algae outbreak. Nitrates have been undetectable since the algae outbreak. Due to the unusual tank situation, adding additional equipment (like a UV sterilizer) isn't possible. Also, since the tank is outside, there's no way to do a 'black-out.'

To read more about my system, go here.

What, if anything, can I do? Would it be possible to use a really fine net to get the phyto out?

Thanks for your help.

What happened to all the mangroves you had in there? They might have been keeping phosphates in check.
I would think that the vinegar dosing might not be taking out phosphates as fast enough as nitrates.
It might be a good idea to cut back on dosing and increase filtration untill you get the situation back under control.

Also, a stronger fuge light might help the algae growth and nutrient intake.

Can you incorporate some phosphate pads/phosban or GFO maybe?

The mangroves weren't doing so well so I had to move them to a bucket with a lower salinity to prevent them from dying. Maybe they released excess nutrients into the system, but nitrates were undetectable the whole time.

I am running Purigen, Activated Carbon, and Seachem Phosguard in the internal filter.

Thank you for the input!!

Does anyone have any experience dosing Hydrogen Peroxide at 1 ml per 10 gallons? I've heard that it can reduce phyto, as well as hair algae.

Thanks!

More pods lol

Yes, or rotifers if you want something that will consume the phytoplankton even faster. And artemia are also good at consuming phyto.
I saw you already had clams in mind. I've seen experiments with cold water clams filtering a lot of green water in short time.

Good luck
