Algae turf scrubber: waterfall or upflow?

I have a 30g system (might attach a new 25g tank)... after reading loads of threads and watching LA fish guys videos (jim himself is using 1 on his system), santamonica ATS and saw on youtube it being used by famous and really known breeders/coral farms/ famous hobbyist, im planning to setup for my system too. im confused between the air bubble up flow or water fall (water fall would be better as all ill have to do is just connect to my system)... The reason is, im planning on it is coz im having some algae issues not major but small ones like cotton candy algae, green turf & bubble algae (i got bubble due to a friend as i bought a coral attached to his LR and i know he had bubble algae never had this prob in 3yrs)... im using GFO, Carbon, cheato and skimmer as current filteration..

Anyone using ATS?? would like to know the size and flow...

Here is some info i found online:
Algae scrubber - Wikipedia, the free encyclopedia

 

im planning on using led instead of cfl/pll...

 

the led lights are not necesirally needed but some people have gotten good growth under them.

santa monica has a websight dedicates to them,Algae Scrubbers to me he is a bit abrasive about some of the new people but has had good sucess with them. it even offers to let you buy a model for a few hundred bucks all you do is plug and play.

literally more info than I could ever need or care to sift through lol

if you have cheto and a current running filtration system a small pump and a five gallon bucket set up would work well for you since it dosent require a ton of room.

 

u using it?

 

not on the 75 gallon I run pellets and use cheto as well as a DSB

I did use a basic one on my 20 gallon though just used a HOB filter to push water acroos a small piece of screen and it grew well on just that.

 

1)Can i use 1w warm white with plant grow led?
2)Can i go for bigger ATS then recomended (as im plannin on attachin a tank to my current setup)?
3)Does it help eliminating pest anemones?
4)i have cheato and skimmer, do i need to get rid of them?
5)im using GFO and Carbon, do i need them too?
6)Will it help geting rid of bubble algae that comes even if the nutrients are low-0?
7)How heavy can i go when it comes to feeding/Stock?
8)Im also facing a small issue of cotton candy and green turf... how long it takes to eliminate all these algae?
9) does it help pod population and plankton to increase?
