Yes i completely agree with you except for the point about the sump... you don't need one ...here have a look at this diagram
and according to me its a lot easier than a sump too.....
some examples of DIY scrubbers ....
Please do have a look at that thread if you haven't already...
im not trying to prove you wrong or anything, after all you've been in the SW hobby far longer than me
You can even build a scrubber in your tank underwater!! Or just in a bucket...the material used for the screen can be virtually anything and there are many benefits of having a scrubber.... I myself feel this is a perfect solution to many of the problems reefers are facing and the working of these has been proved 1000´s of times. again i am not speaking against you or anyone else. All im saying is that these are what i think is the perfect solution to many problems facing reefers today.... benefits of an ATS include
o Allows you to feed very high amounts without causing nuisance algae growth in the tank.
o Can replace waterchanges, IF THE PURPOSE of the waterchange is to reduce nitrate or
phosphate or algae growth. Otherwise, it does not replace the water change.
o Grows swarms of copepods.
o Increases pH.
o Increases oxygen.
o Will NOT spread algae into the tank. It removes algae FROM the tank.
o There is no odor from the algae (only a slight ocean smell when cleaning it).
o Is very quiet when flowing, similar to a tabletop decorative waterfall.
o Introduces no microbubbles when adjusted.
o Removes ammonia too.
o You can even make a portable bucket! Just unplug the lights, lift up the pump
out of the tank water, and go put it in your next tank (or your friend's tank).
Don't let the screen dry out though.
o Works in saltwater or freshwater.
