I tested my water reservoir, tested out a 0.03 ppm. Which is cool.
Not really. I would trip out if my barrel was .03,
What TDS is your ro water? I sure hope for your sake the barrels arnt leaching anything

So there are three options:
1. The salt that is mixed in there is bring some residual phosphates. I use Instant Ocean "regular". (I will be moving to Instant Ocean Reef Crystals as I am on my last box of regular IO)
2. The tank is leeching. It is a polyethylene tank so it is inert. I cannot see this being the issue, but I will test my RO/DI holding tank to narrow things down.
3. My ro/di is not working properly and I am getting some phosphates from the water itself.
Mind you 0.03 is far better than what my tank is right now anyways, and getting to anything under 0.05 will be my short term goal.
