Increasing oxygen with phytoplankton photoreactor

[sixty_reefer]

Most likely the advantages won’t get any merits although would diverting the oxygen created by a phytoplankton culture aid with oxygenation and oxidation in a reef tank?

here’s the current set up, a simple photoreactor that is sealed and all the air is being diverted to a lime wood stone protein skimmer, my thought is that phytoplankton will be utilising co2 and releasing O2 into the atmosphere during photosynthesis. Would harvesting the phytoplankton culture oxygen production have a similar effect to hydrogen peroxide on a oxydator reactor?

on a side note: I got a feeling that this also be on MACNA next year :p

Phyto (and algae ) is very complicated. They produce organics that feed bacteria, they produce anti fouling agents that are toxic to bacteria. They produce reactive oxygen species that have positive feed back loops, they produce reactive oxygen species that have negative feed back loops. Looked into it 10 years ago and none the wiser now. I hate algae :)

Wouldn’t oxygen just be oxygen, what do you mean with reactive oxygen?

If I am not mistaken this it what some manufacturers aim to produce when selling devices that produce micro oxygen bubbles through electrolysis. These devices target planted tank aquariums and their objective is to inhibit algae growth among other things. Here are 2 examples:

Last time I looked biologists don’t understand the interactions between algae and coral in the ocean. Now, the interaction between algae and coral in a glass box?

To be perfectly honest I have my doubts about those devices and what these manufacturers claim. In fact in the planted tank community these devices are perhaps the most ambiguous devices and they have generated the biggest threads and a lot of doubts persist on their actual efficacy.

Humans think we are clever, the truth is we are not.

Many folks utilise söchting oxydators in the reef hobby I have never seen the benefits myself although many seem to believe that it works similar to ozone, just safer.

Why not just use am oxygen reactor?

 

[LovinlifeinGuam]

Also won't that raise the BOD having the opposite effect?

Not sure how it would affect the biochemical oxygen demand

Due to most likely just being as useless as this.

Well as long as you're very careful to monitor the reactor it might be fine but in natural environments phytoplankton blooms ultimately deplete oxygen as they die and decompose which leads to lower oxygen concentrations...using it in a reactor may be safe though...just a thought

This happens due to CNP in phytoplankton, basically due to carbohydrates which are sugars.

I made some observations in this thread on that subject

https://www.reef2reef.com/threads/u...hytoplankton-to-carbon-dose-my-system.926040/
In this thread I was just mentioning if the oxygen harvested from a phytoplankton culture could have any oxidising affect in a system like ozone and oxydators do.

If it does have an affect on oxygen it'll cause a bigger swing in your pH when you turn out the lights due to the photosynthetic process (or do you plan to keep the light on?)

I haven look at ph I thought that the amount of oxygen that would come out of a phytoplankton culture not be enough to make a big deal, nevertheless I do run the lights on the photo reactor 24/7

A vast majority of oxygen produced by photosynthetic organisms is O2.
Oxidizers used to target organisms and solve problems are things like ozone, peroxide, hypochlorite, chlorine dioxide, etc.

These are far more reactive than O2. So they shouldn't be compared.

Yes, photosynthetic organisms can produce small amounts of reactive oxygen species like superoxide radicals etc. But they also contain quenching mechanisms to remove those. @Garf referred to these complexities earlier.

I would not recommend hydrolysis of seawater for a reef tank. Too much risk of chlorine and other undesirables.

It may be a fine way to boost O2 and drop CO2, but adding O2 will not have the same effects in seawater as hydrogen peroxide that is more reactive than O2 and also acts as a reducing agent, which O2 never does.
