hi new 40 gal marine tank help please

is a 180 litre marine tank easyier to maintain than a 60 litre?

 

hey chadley
a 40 gallon tank is better than a 16 gallon one IMO

so you only want fish? no corals?
if so - a twin T5 light fixture would be ideal - if you want corals 4 lights T5 would allow you to keep many corals

fish stocks - for beginners 1 inch of fish to every 4 UK gallons is recomended so that means a max of 10 inches of fish - allow for max size and not the size you buy them at

a yellow tang is not a good idea for the above reason , they grow big quickly and need lots of swimming room

with a 40 gallon tank for just fish I take it no sump?
I would use dead base rock, dry sand - have 2 x Korallia or other wide spread wave maker devices like Seio or tunze one either end and have an external cannister filter either Fluval or Ehiem (personal favourites ) so I could run carbon and GFO coupled with a good HOB skimmer such as AquaC remora, or Deltec brand

but if you do run that external cannister filter - part of your weekly maintenance routine needs to involve opening it, removing and rinsing the trays and media bags in old tank water at time of water change



fish species assuming in some cases no corals - dwarf angels for example are hit and miss with corals
clowns
royal gramma
dwarf angels
blennies
gobies
cardinal fish

avoid any species with specialist feeding requirements early days in the hobby IMO

hope the above helps alhough now its seems the answer "Yes" would have been more appropriate

Generally speaking, larger tanks are better then smaller ones because parameters are generally more stable. IMO, no marine tank is easy to take of. You can automate a lot of things such as auto top off systems, auto dosers but you still need to test and care for the tank. I would go with the larger tank then a smaller one, especially for a beginner.
