Post an updated full tank shot
I’m curious to see how much the mass has been allowed to grow if it’s been left in place, and the same sandbed, since oct
Seeing how the invader handled this time and the partial actions against it in an updated pics is gold for tank tuners
Ideal would be two pics side by side, one from nov or so, and one recent one so we can see unspoken details
Leaving an invader in place and taking incremental action works sometimes, and removing the entire invader by hand, then taking regrowth preventative action works all the time, but those with massive tanks can’t do that much work. This tank wasn’t massive from what I saw on the blackout pic
Removing dino cells by hand from your system never causes more dino, starving them sure might, and correct pre removal should precede any uv install. Hand removal is incomplete and leaves cells for growback, but not in a crazy virulent state and that intercept point is critical. When their mass is low
You want the initial mass reduced and removed before taking mitigation action if you have a tank size that allows it, and as I read you’ve have four mos to try the leaving it in the tank mode, pics show us how it adapts over this time. There is not a single biological reason not to take forced control over where dinos are hiding in repose in your system (sandbed suspect, pics)
Even if you want an exclusive N and P system of approach, you do not have to run that in the fully invaded condition.
Nano reefs are made invasion free this way all the time, you just have a few more gallons.
