Don't worry... I think your rocks are still leaching nutrients... it's normal btw... give it 2 to 3 months
Another aspect to look at is flow... do you have sufficient flow?
Yes... once in a lifetime Perhaps when I upgrade to my next mega project... right now I have too many Tangs already... I do not want my $20 Kole to kill the Gem Tang
The fish is quite big... at least 3.5" in length
In hiding (as expected) the whole day today... can you spot it? Now stop staring at my Maxima It's not in there
Long time never update this tank... here's a video of my Red Head Goby
There will be major transformation to this tank in the coming weeks... something exciting I hope
That's already a great improvement bro... if you measure your NO3 from your tank water (not discharge from Denitrator) then 5ppm is not bad at all... don't worry too much about bringing it down to zero
Rare fishes at Irwana... still got a few pieces of
Rhomboid Wrasse
Helfrichi Firefish
Mystery Wrasse
when I left the farm around 12pm this afternoon... some very nice Bartletts, Flame Angels and exquisite-looking Black Perculas too
