[nanomania]

Guys mine is a sumpless 450l (120g ttwv) tank.
Fishes will be
2 gobies
2 tangs
2 oc clowns
2 bangais
1 yellow coris
Few inverts.

Im confused between these 2 skimmers classic hob 2000 (the box shaped) vs classic 90 (the normal cylindrical shaped)

You have to have a sump with the classic the 2000 hangs on the side of the tank

I have 90 in a 30g and it works very well

My bad I thought the 90 classic was the older model of the 110 that I use, disregard me

Hob classic 90 is recomended for 120g to 150g
