How to Calculate Tanks Size

[Marks]

Working out how many litres amount of
Marine fish
I have 170 litre main tank plus 100 litre sump does this make 270 litre worth of fish

[David S]

No,calculate it as 170,its more the size the fish will grow too rather than fish/ltr.

The sump will help maintain good water quality in a heavily stocked tank, but you still only have 170L of physical space for your fish.

Have had tank drilled 2 outs in weir
Drains into rowa carb bag then into skimmer section, which flows into
7 inch DSB then into return section with return pump . I also have a fluval 405 that outs and return to this section .
Would you put a rowa phos in a fluid reactor or put rowa phos in my fluval 405
And what other media would you have in
My fluval
