Algae Scrubber Basics

This is mistake.
No, it's not. Are you in the wrong thread? This one is about algal turf scrubbers, not about other macroalgaes.


(though, I've grown many macroalgaes, and switching from a 4500K white LED setup to a 660nm and 450nm setup I experienced a significant increase in growth, showing that this combination with the same PAR is more efficient at growth).

You are all mixed up - srubber algae, and algae in the bay sump.
I will not argue - I told only my opinion.

We can all have opinions, and that's fine, but your opinion doesn't match up to the results.

Have you actually tried using narrow bandwidth vs 'full spectrum' over an algae scrubber or a macroalgae refugium?

I'm growing algae just fine, and in huge amounts, under 660 + 445
 
Not that I agree with him, but i believe that he is suggesting that GHA alone is not sufficient to balance the system. He implies that you need a diversity of algae growth on the scrubber to achieve this balance. Perhaps one of you could illustrate (again, since I know it's been covered in a variety of forms in this thread before) how the GHA alone can and does out perform the other algae types and that it does indeed provide stable and balanced nutrient levels...
 
I'm talking about the advantages of algae scrubber!

For example -
Makroalgae refugium stop the growth (algae stopped growing - hopefully you quadrupeds such cases) and algae scrubber continues to grow algae.

Quotes from the Internet -
In addition to chlorophyll in the membranes are also present carotenoids, yellow, orange, red or brown pigments additional modifier which absorbs certain portions of the solar spectrum, the energy of these beams is transmitted chlorophyll molecules. Thus, they facilitate the use of the rays that are not absorbed by the chlorophyll.

The properties of the lower algae that grow those species for which there is food and a range of sun!

At different depths grow those types that have adapted to the conditions.Each alga requires an individual composition of sea water consumption - each algae need in an exclusive part of the sea water.
This is appreciated and algae scrubber.

This is the value of the algae scrubber - aligns the parameters of sea water due to the many species of algae.


And more theory -

For such purposes - LEDs for illumination printing premises (a high index of color!)
Do not confuse a full spectrum of light - a dense spectrum of light!
Three thin peak RGB - does not mean good filling of adjacent spectrum.

Do not look at advertising spectrogram - see real indications of measurements in the laboratory!

Top (metal halide), and the bottom LED.

Do not they will be able to grow algae that require that the dark areas (bottom LED) of the picture.

Your theory makes sense in the idea of growing vast kinds of algae, but the point being made by Turbo is that we don't need all of these algae types in order to balance our reef tanks.

Do you know of any that actually do? I certainly don't. They all contain chlorophylls a and b, which absorb primarily at 430nm & 660nm, and 450nm and 630nm, respectively. They have accessory pigments that are used to capture more light using a bit more spectra IF they are not able to capture enough of the listed above during the illumination period. If you give them enough of what they need using specific spectra, they would have no need to use their accessory pigments, otherwise they would not be accessory pigments and would be primary.


I have grown all kinds of macroalgae under 660nm/450nm. Chaetomorpha, gracilaria, bryothamnion, four or so species of caulerpa, codium, halimeda, galaxaura, padina, ulva, botryocladia, halymenia, and probably several others that I am forgetting. Every one of them had significant growth. You keep trying to tell us that it is impossible to grow algae under anything other than basically sunlight, but that is simply not true.
 
If you say things often enough, it becomes the common knowledge or lore, based on repetition alone. Actually the short turf alga grows fastest in the right high energy environments. It is hard to achieve optimal growth rates.

GHA may work best in most common scrubbers. It grows plenty fast enough but it is not the fastEST. What it is, "¦is that it is more convenient and easy to grow, easy to harvest. That is why you want GHA.

Regardless of energy levels, lighting, flow rates and screen matrix that you have, typically, there will be a dominate algae that likes to grow in your scrubber. You can play around with those conditions to get or change what you want but very often each scrubber will have more of one type at a time rather than a highly divers garden so to speak.

There aren't a lot of peer reviewed studies on red and blue yet and the older ones point to white light but I look at what professional growers are using now and that is what they are doing. Personally, when I restart my scrubber, I will go along with the crowd and have mostly red with a little blue because those are the primary requirements for plants in general. I'm going to go with the pros.

I will however, also have a smidgen of white as well, just in case. Go Figure
 
You have not understood correctly.

I do not say that under the LEDs will not grow!
In hydroponics great use LEDs.

If you read my post again - you see what I'm talking about the alignment parameters of sea water by growing many types of algae.

Different species of algae - absorb various micro and macro elements!


I wrote above -

For example -
Makroalgae refugium stop the growth (algae stopped growing - hopefully you quadrupeds such cases) and algae scrubber continues to grow algae.

Аn example of which can only algae scrubber - avoiding mass growth of diatoms, etc.

If this statem is provably true then Vladec, if not, then every one else is correct - you only need GHA.

Show us the studies one way or the other. If not, then it is only opinion.

Can it be demonstrated that tanks are better of now than they were 5 or so years ago, before LED's became the fad. I did the LED thing with the DT lighting, and have gone back to MH
 
It's the nature.

If I understand the processes in the marine aquarium - I gave up on the algae scrubber. Aquarium looks just as good.

The aquarium 102g - 1 pump flow 2 heater 100W, Light (150W MH + 2 T5 + 7pcs. LED Blue)
No more equipment in the aquarium there.
 
Hi All, taking a keen interest in this thread.

I do not have room for an algae scrubber, so was wondering if rigging up a submerged screen within the second section of my sump with adequate lighting would do the trick?

Does the algae need to be out of water - It seems to do very well submerged in my DT lol

Also, and finally - would a 24 hr photo period / alternate photo period to DT be preferred?
 
I need a little advice. I have had my ats up for a little over a month. I have harvested it three times. Everything appeared ok until my last harvest. Ever since then it seams to me that I am growing cyano with tufts of gha. On the edges I can see some air bubbles. My sump is starting to grow it in there too. I have a little on my sand bed that I have been fighting for a while but nothing to crazy. Should I put some Red slime remover in and treat the tank? Or just let it keep going the way it is?
 
I think vladec is saying that to emulate the natural filtration of the ocean the closest, then a variety of scrubber growth would do that.

If underwater (i.e. the upflow versions) you will need bubbles to get rapid enough growth to filter. This is what generates the thin air/water turbulence layer that works best.

growing cyano with tufts of gha

Sounds like a weak light.
 
The main task is not the weight of algae - the main task is variety of species of algae!

Full spectrum light is required for the growth of different species of algae.

Different species of algae consume the different composition of micro and macro elements from seawater.

This allows you to align the performance of sea water.

For example -
Makroalgae refugium stop the growth (algae stopped growing - hopefully you quadrupeds such cases) and algae scrubber continues to grow algae.


P.s. to SantaMonica - yesterday was going to register on your web site and discuss this issue - unfortunately I could not find the forum :(
