Probido-what can it do for me?

[Nano]

Well where to start.

As some of you may have been reading in some of my recent threads I've been having minor issues with slow growth and browned out sps. After a few months of playing around with flow/lighting I haven't seen and change. I have noticed that some sps that shouldn't glow under actinics glows quite well in my tank :P so I have come to the conclusion that the zoox they are displaying is more from nutrients then lights and flow as said I have tried to lower and raise the lights, and same with flow. It's just recently that I have been looking into zeo and probido, however after measuring the sump as well as my wallet, zeo is not going to be an option at this time.

I have been reading aquadigitals probido thread and it seems this could be a more tailored to my needs. Anyone have any tips, opinions or experiences with probido? I would like to get this color back and the growth going again. I thought maybe my RO filters were bad, so I bought a tds meter and it comes out clean at 2ppm (at least that's what I think I'm reading) and last time I flushed the filters it was 0 so any help is appreciated as always thanks everyone.
