Quick update on the the ugly phase of the 50 lagoon. A few days after that last pic it started to get really ugly. It started to get dinos, slimy bubbly brown yuk. I dosed ammonium chloride (aprox 20% of a start up dose) and it all turned to long stringy green hair algae in just a couple of days And the bubbles went a way.
then I added a few hermits and snails less than two weeks later it looked like this and still does.
I still haven’t even turned the skimmer on yet. Keep in mind this is dry Fiji not Marco so it was some dirty rock and I think that is actually a benefit as it keeps the tank from being too clean at start up. Last time I bleached then soaked the rock for months before starting and kept the lights off for weeks and it was a miserable start up.
So much easier and faster than last time even though I am still using the same rock. I think the worst thing for a new tank is to be too clean.
Key differences I did this time
1) Hit it with full light from day 1 (intensity and duration)
2) did not clean rock first
3) did not start skimmer (still haven’t)
4) added ammonia (again) at brown yuk phase (get green algea growing soon as possible, don’t want to see anything brown growing)
5) add CUC at rite time.
