Mega-Powerful Nitrate and Phosphate Remover Replaces Skimmer, Refugium, part 1-4

It's about DOG DONE time. :) Looks great. How's the crowding? or is most of that LR?
 
o Put a wavemaker (on-off-on) timer on the pump to simulate waves; gives the algae more
air between the flows. I used the JBJ Ocean Pulse Duo timer ($50 new), and set it to 30
seconds. (note: this timer has a quirk: if you cut the power to it, then restore it, it
keeps the pump "on"; to get the on-off-on function working again, you have to turn the
dial to the left and back again.) (from santa monica thread section 4 of 4)

i can't find any timer that can control less than a minute...
what if the water flow stop for a minute and run again for 30 minute.... thanks

in this topic i read interesting
"Algal filters in general, but especially turf scrubber systems tend to color the water with compounds released by the algae. The original turf scrubber systems developed by Dr. Adey gained a bad reputation because they did not employ skimmers or carbon to help control these compounds. "

can you explain about this???
