It's fine aragonite sand.
I poured the sand into the tank, filled half way with fresh water, stirred the crap out of it and drained about 5 times. Each time stirring it up.
About the 5th time it was looking pretty clear.
At that point i drained again and filled with salt water.
Today, I drained 55g into a drum and replaced with fresh water because the salinity was too high. I followed the directions but I believe the sand had alot of salt attached to it, throwing the whole thing off.
At the moment, i have a powerhead in a temporary tub
pumping slowly to test my overflows and plumbing for leads.
The overflow is passing the water thru filter material and coffee filter. (what the heck, ill try anything now).
Do you think an investment in the fluval would be a good one?
From the start, I did not plan to run mechanical filtration. Does anyone else run them from time to time to clear up the water?
Thanks for your advice.
