Grigor's ATS Version 2 (1 Viewer)

A long needed update. Next week will be the 3 year anniversay of 180g show tank being skimmerless with main filtration being ATS + water changes. I also do dose some LaCl3 to better maintain phosphates in addition. So no, ATS alone isn't solving everything but it is the main component for my system.

Tank phosphate levels had been going downhill since Sept./Oct. timeframe approaching .18ppm. Rocks nots as clean, more slime and cyano. No hair algae but tank was showing signs of going down hill. The ATS screen had not been producing as much algae and what was growing on there was more slimey than anything.
Several reasons, 1 got lazy and wasn't harvesting every week, second I forgot and left flow off for an full day and dried it out some and never was the same afterwards.

Meanwhile the ATS on the 75g ( which recently upgraded to a 120g ) then algae was very healthy green/stringy.

So I decided to scrap the screen and start over. I took some of the algae from the 75g and transplanted to the new screen. Within 2 weeks the harvest was already larger than was prior to the switch.

Now just 4 weeks since its already as good or better than the peak it was with the old. No more slimey, mostly scringy, I sqeezed out as much water as possible, rinsed with ro for smell. I got over 2 cups packed as tighly as possible this week.

Phosphate reading this morning is 17 on ULR checker which = .0522 ppm. For my tank, it seems to do best and I usually target .06- .08ppm. So slightly under my target range. Tank is doing awesome. I'll snap a tank pick later today.

For now, here is the harvest. 1 side, I alternate cleaning a side per week so the growth equals 2 weeks. I have done weekly harvest Sunday and Wedesday before and haven't found one yields anymore than the other so just do 1 cleaning per week:

1/26/2015: Largest Harvest yet. I have switched from a 1 40g water change per week to every 2 weeks to try to cut Salt costs. I'm sure that has something to do with the growth. Tank though as never skipped a beat still looks better than could every hope for. I'll snap a full tank shot later today.

I normally harvest 1 side per week. However the 1 week old side completely caught up to the 2 week old side. It was so full and heavy I had to harvest both sides. You can even see on the side it was so heavy it ripped the screen at the top.

Last Pic, Algae was rinsed and sweezed and packed into the measuring cup as tight as I could, I even heard the plastic cup start to crack from my pressure.

Side A: Two weeks old:


Side B: 1 week old:

Harvest after rinse, sqeezed, and packed tightly:

Every time I see David's tank I think about doing an ATS. Great results as usual David.
 
I don't get how green and 'fluffy' it is. Must be actual turf algae, all I ever got was stringy/slimy stuff.
 
Still growing insane amounts and very thick. I hate to do it but probably need to replace the screen, between taking it on/off and so thick and heavy the screen is getting pretty ripped and now water kinda squirts out more.

I've got the acrylic to build a version 3. Only real reason to build another one is the union fitting to take the screen on/off is on the outside. There has been at least a half dozen times that it drips unknowling from not put back on quite tight enough to seal. Several days later enough has built up to cause a mess. So next version will have a built in drip tray so to speak so any drips will just go back into the bottom of the ats.

The ATS I built for the 120g tank it's a non-issue because the union is above the sump so if leaks it just drips back to the sump. But the 180g can't be designed that way since sump is a tub.

I also thinking about trying LEDs again. I have most of the parts but would need to buy more ballasts. That would cost about $40 each side and got these off ebay for $100 each and dimmable so I figured I'd put that money towards these instead. Should arrive in about a week: http://www.ebay.com/itm/151570300187 Screen is 18" wide and the fixtures are 16" wide so should be a good fit.

Seems like a really, really big light for an ATS. Dim-able is certainly nice (and probably really needed on this one). Any idea number of the different leds are in there? From the pic I assume its mostly red, but unless I missed it the description didnt' say.
 
That's a really lighting interesting option. When I was looking at ATS's again I went a few email rounds with Floyd (Turbo Aquatics) and the lighting bill alone for 36"x12" coverage (both sides) was well over $800 to do it right. For $200 bucks could be done with these and their plug'n'play. Technically if wanted to cover 36" then might either need double the units or the 600w models but still at $400 completely assembled that's not bad.

Patent- looks like 100 pieces (3w LED's) across 9 different spectrum. For a lawyer, you no read well not much. :)

Marty, u rube, merely stating 100 LEDs across 9 different spectrum does not tell you how many LEDs there are in each spectrum. It leaves thousands of possible permutations. 90 UV LEDs and 1 red one gives you a very different light than 90 red leds and 1 UV LED. Given you are trying to grow algae, the spectrum does matter. Not to mention it only lists 8 of the 9 purported bands, and "white" is rather non specific.

Don't lecture me on reading before I send Angie over to read you the riot act. Though I dunno, you might like that. So never mind.

Yup, story checks out. BOD & lawyer therefor rules don't apply to them.

I also thinking about trying LEDs again.

Hey David - since almost all of your original pics are broken links, any chance you might take a couple pictures to show off your scrubber and lighting setup as it exists right now? Before you go and change things up with LED's and everything?

Current version is 4X24W 3K ( soft white ) T5 Bulbs. Notice the Union is on the outside, any drips they drop on the floor. Many times it doesn't seal perfectly ( not tight enough ) and slow drips and don't realize until enough has happens to cause the carpet to get wet. Summer time especially the concrete sweats, I used to have a leak frog on there but so many false alarms, I should put it down for winter but never remember to do so.




ATS album has the LED version I used prior:

Easily retrofitted. The nice thing about the workhorse ballasts is don't have to rewire. Just removed the bulbs on one side and sat the new fixture in.

Full strength the 300W LED fixture is really just 122w on the watt meter. So that's all marketing becuase it has 100 3w leds.

I initially dialed it down to 30w using a watt meter. Will see what happens and go from there.

Picture has one side 2X54W 3K bulbs, the other side 1 of the fixtures. Will give it a little while to compare before change the T5s out completely.


The best I can tell it has 2 white leds, 1 Infrared, and several blues. I'll just stick some tape over some of the colors if algae doesn't grow in those areas.
 
Please remind me how 100x3w LEDs at full intensity only equals 122w. Don't get me wrong, this is great news in the electricity usage department I just would have thought this thing wide open would have been 300+ watts.
 
A 3W emitter may be driven at approximately 3W but does not have to be.

As the LED is driven at higher power levels, esp. closer to its max, the temperature increases and its efficiency decreases. As the temp goes up, the lifespan goes down. So, while a 3W LED can be driven at 3W, and 100 of them could give you 300W, its often far more efficient for the amount of light you want to drive it lower by running a lower amperage through them.

Think of it as a dimmer switch, by choosing a different ballast or driving it differently you get a more efficient light. Most of these cheap lights don't tell you what they actually drive the light at because 300W sounds much better than 122W
 
What has the world become when you can't trust Chinese marketing.

Thanks for the recap, I know all that (electrical side). What I didn't know, or think of readily, is how LED products are marketed as you indicated. For lighting, I still think of lighting and linear/watts equals output. That's not the case which LEDs but I just don't have that burned into my brain.
 
First week harvest of new LED fixture side.

Overall growth rate seems to be comparable to the T5 side. Visually can't really tell much difference. I didn't think ahead and seperate the algae harvest from each side to compare.

I has a little more yellow which can be the lights or the screen just didn't get quite the flow in that area. So really inconclusive at the moment.

Going to ramp it up from 30w to 35w using watt meter to adjust.
