Is that surface film I spy or just lighting doing weird tricks on the water surface? Also, what are those white blotches in the front in the soil? I like how you can see the HC growing outwards along the substrate...always a good thing to see. Looking forward to a Mini M of my own hopefully in the near future.
Yes, that is surface film you see. It'll start to level out and appear less and less as the growing matures. Once water changes are at the three day stage ( starting after tomorrow's water change ), I'll end up stirring it up a bit more in between changes.
The white spots is where I was stupid in dosing Penac W - over time it will dissolve completely, but sometimes when you don't dose it appropriately it will catch itself lower in the substrate. Not a problem for anything, just a technique in dosing it.
