I figured I make a separate thread regarding the results I've obtained so far using the LED pucks I posted in my build thread. I think, for those who would like to use LEDs but do not either have the ability or inclination to do the soldering and wiring, these 4 diode pucks do the job. All one needs to do is mount them and connect them to an appropriate power supply. It was very easy to do. The pucks are also very thin and may be beneficial for those that have a tight space to work with. They come wired on a string like holiday lights and you order what you need. I purchased all red, but they do come in other colors and can be combined, though that would take splicing them together.
This is the second cleaning and the results do appear to be very successful. It's 13 days after the first cleaning was performed. As of now my tank does not have much of a bioload. It's just a week or so past a full cycle and the only tank inhabitants are a cleanup crew of 8 hermits and quite a number of various small snails. I have not been feeding the tank. I wanted to see the levels stabilize before proceeding. The tank was established with live sand and recycled live rock from my prior build that I basically turned to dead rock via the standard "cooking" practices. The rock was infested with all sorts of baddies and I wanted to start over.
It appears the ATS is working and doing the job of pulling nutrients as PO4 is reading zero and NO3 is at 3ppm. The tests used were Red Sea Pro and a low range Hanna Checker for a confirmation of the PO4 reading.
The following pics exhibit the results to date.
