The worlds first Spiky Screen Surge Scrubber. Obvious improvements still to do, lighting, laminar flow baffle plate, roughing up cable ties etc. Day one;

Awesome!!!!!!

[C-Horse]

Cool. How about 3SAS as an acronym? or S3AS, for S.S.S Alage Scrubber?

[tebo]

Really nice,, video pleas

[RkyRickstr]

Ditto on the video, need to see this in action.

[Floyd R Turbo]

How about Snake. Ssss...get it?

A video will be shot when I've finished tweaking with the setup.

[sklywag]

Come on now. You know on this site we don't care about perfection during trial and err stages. We want video.

The 5th day;

[sabbath]

Nice 5 days of growth!

[Floyd R Turbo]

Looks like the light is white/blue?

[Garf]

Looks like the light is white/blue?

Oh yeah. That's just a reflection off my display halides, the actual algae light is a single standard 23w 2700k cfl. Got foil around it most of the time so I can run it at night now. Still not an 18hour period yet, maybe next week, there's no rush, after all :)

Day 8;

[donkey]

Is that growing off the cable ties

[Garf]

It's growing from the plastic canvas at the minute, but I see no reason why, after time, it should not use the ties as a substrate. Hence the "All Dimensional" reference. That's the plan anyway. As you can just make out from the pic, they've started to change colour.

[donkey]

Looking good,i cant see any reason why it wont start growing off them cable ties

Abstract

Worldwide, many marine coastal habitats are facing rapid deterioration due in part to human-driven changes in habitat characteristics, including changes in flow patterns, a factor known to greatly affect primary production in corals, algae, and seagrasses. The effect of flow traditionally is attributed to enhanced influx of nutrients and dissolved inorganic carbon (DIC) across the benthic boundary layer from the water to the organism however, here we report that the organism’s photosynthetic response to changes in the flow is nearly instantaneous, and that neither nutrients nor DIC limits this rapid response. Using microelectrodes, dual-pulse amplitude-modulated fluorometry, particle image velocimetry, and real time mass-spectrometry with the common scleractinian coral Favia veroni, the alga Gracilaria cornea, and the seagrass Halophila stipulacea, we show that this augmented photosynthesis is due to flow-driven enhancement of oxygen efflux from the organism to the water, which increases the affinity of the RuBisCO to CO2. No augmentation of photosynthesis was found in the absence of flow or when flow occurred, but the ambient concentration of oxygen was artificially elevated. We suggest that water motion should be considered a fundamental factor, equivalent to light and nutrients, in determining photosynthesis rates in marine benthic autotrophs.


There are two possible pathways by which oxygen accumulation inhibits photosynthesis (2 (http://www.pnas.org/content/107/6/2527.full#ref-2),4 (http://www.pnas.org/content/107/6/2527.full#ref-4)): (i) photorespiration, involving enhanced oxygenase activity of ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) (20 (http://www.pnas.org/content/107/6/2527.full#ref-20)), and (ii) the production and accumulation of reactive oxygen species (ROS) (4 (http://www.pnas.org/content/107/6/2527.full#ref-4)) through such processes as the Mehler reaction (21 (http://www.pnas.org/content/107/6/2527.full#ref-21), 22 (http://www.pnas.org/content/107/6/2527.full#ref-22)). The latter pathway is most pronounced under conditions of extreme temperatures or excessive light (4 (http://www.pnas.org/content/107/6/2527.full#ref-4)). Photorespiration is expected to occur when the internal concentration of oxygen is sufficiently high to effectively compete with CO2 as the substrates of RuBisCO (23 (http://www.pnas.org/content/107/6/2527.full#ref-23)), a key enzyme in photosynthetic carbon assimilation.


In all three species studied, the onset of flow led to significantly (several-fold) enhanced photosynthesis and a substantial (32%–45%) reduction of oxygen concentration inside the organisms (Fig. 1 (http://www.pnas.org/content/107/6/2527.full#F1)). Differences between flow and no-flow conditions were highly significant

http://www.pnas.org/content/107/6/2527/F1.large.jpg


We conclude that photorespiration, driven by the use of oxygen instead of CO2 as the substrate for RuBisCO, was the principal cause of the decline in photosynthesis under no-flow conditions. Whereas the species examined had different types of RuBisCO with differing affinities to CO2 and O2 (23 (http://www.pnas.org/content/107/6/2527.full#ref-23)), in all three species low internal oxygen enhanced photosynthesis (Fig. 1D (http://www.pnas.org/content/107/6/2527.full#F1)).

Day 9 and the GHA seems to be taking a hold on the cable ties;

[donkey]

Did you Rough-up the cable ties on both sides

[Garf]

Did you Rough-up the cable ties on both sides

No, just the flat side. Left the clicky side as it was.

[donkey]

Which side does it seem to be growing better on ?

[Garf]

Looks like its starting on the rough side then spreading to the other side, once it's got a hold.

[donkey]

Wonder what it would be like if you rough-up the clicky side as well

[Garf]

I think you would only be able to do that after putting them on the screen, but didn't want to knacker them up before proving the principle. If the principle does in fact hold true, I'm sure there are more efficient and better ways to provide a substrate in 3 dimensions. My way is probably one of the worst ways of doing it, but the cheapest and fastest I could think of :)

[donkey]

How about using some thin strips of the plastic canvas roughed-up and cable tie them down to the plastic canvas instead of cable ties

[Garf]

If you could get them to stand up and take a fair bit of abuse from harvesting, then yes :)

[donkey]

If you cable tie a few strips together will they stand up

If you configure canvas strips like S or U , they will stay erected just fine :D
Strait line will fold as expected like old mans you know what. ...

That is interesting. IMO all that is really needed is about 1/2" or less protruding from a vertical screen. But then again, this may fall under Adey's patent potentially.

That is weird.

That is weird.

you may also be correct about the height of the cable ties on this horizontal. If no benefit is found with the long ones, they will be getting the snip!

[Garf]

It's got thicker, but not a lot of extra height;

its seem like pubic hair too LOL

well nice grow Garf!

[itzrulez]

with low flow, that would be a really nice place for breeding little fishes right?a lot of micro life!

[donkey]

Who do you know that has Green Pubic Hair

:eek:
