OK. Next stage ‘challenge the theory’. Last time I was in the hobby (10 yrs) the logic was that tank capacity was based on inch of fish per 5 gallon if memory serves me correctly. Given all the fantastic improvements in the hobby I was wondering if the capacity of the tank had been revisited. I am in the process of putting 1 inch sand in tank and around 25kg of rock in the tank (RSM E260 with sump). Run refugium with cheato. Skimmer rated to twice tank size (it’s what came with it) usual sponge and socks and the obligatory carbon. Thinking of doing Triton method but not committed yet. So what’s the modern take on capacity. Will it still be 16 inch of fish for the 80 gallons I have (sump and tank combined) or something different and up to date.
