Tank is 4 months old this weekend. I've been doing weekly 20 gallon water changes for the past 3 months. The glass and water column are filled with pods.

I'm starting to notice a bright lime green coating on my base rock. Does not appear to be on the few pieces of live rock that I have in the display. I've read that this could be the start of some coralline but I did make the mistake of rinsing the rocks and sand in tap water back when I first set up the tank so not sure if the rocks are leaching something.

Still no fish in the tank yet, just a CUC of Nerites, Ceriths, Emeralds, Hermits, Porcelain crabs.

I drop a small pinch of New Life Spectrum pellets in the tank about every other day or so.

Here are my current parameters:
Nitrate: 1-5ppm
Phosphate: 0.03ppm
Alk: 143.2ppm (DKH 8)
Cal: 460ppm
Mag: 1470-1500ppm (just started testing for this so not sure if I did it correctly)
PH: 8.0-8.5
RODI water
TDS: 0ppm


I'm also running carbon and GFO dual reactor
Instant Ocean Reef Crystals

All feedback is appreciated. Thanks!

Same thing happened in my tank... the lime green coating will go away on its own.. heard a million different reasons as to why this occurs from phosphates leaching out of the base rock to who knows what..

Anyways, I didnt do a thing an after a couple weeks it was all gone..
