Trying Polyp Lab's "System Reef-resh" this weekend.

[Jaws]

I think it could have a little to do with the undetectable amount of nutrients in our tanks that can't be measured by a $20 test kit. When I first read their requirements I thought exactly the same. However, I think that this product, if it works, might just take an already optimal tank condition to a new, slightly higher level ensuring a slightly higher level of growth and overall health. Sounds like it could be a good product if you don't mind paying a bit extra to get a bit extra. That's how I've interpreted it anyways.

My question is, theoretically, if you didn't have optimal tank conditions, and still had some nutrients in your tank that was causing algae growth, should it not still export the excess nutrients and help starve the nuisance algae?
