first will a tank 910*450w*360h be ok with a sump set up.

also do you need a skimmer straght away or can you run it with out one.

im think may be cold water set up.

any idears will be helpful.

Cold water is good to start with if you are near the ocean, not so expensive to lose stuff

in the past i have started tanks as cold water local

then after running as cold for 6 months or so have heated and stepped up to tropical

not so expensive if i made a mistake

That size is OK. Small, but can work.

It is not absolutely essential to have a skimmer from the beginning, but the sooner the better.

360 high can probably get away with T8 lighting?

And 450w is good, my 380 is too narrow

If he's going with cold water he won't need any real lighting.

if i was to go tropilcal what would i need.how many fish can i have.they say marine is easy than fresh water.how does that work??

also the tank910*450w360h but it tapper to the top at 570 also i have anthor tank the same and jion yhe two together.and mount the rock on the tapper part of the tank

if i was to go tropilcal what would i need.how many fish can i have.they say marine is easy than fresh water.how does that work??

Have a read of the beginners guide sticky, you should get an idea of the requirements to go tropical marine.

Who is telling you its easier? Not sure how that works, I have found it to be more work - extra maintenance requirements, more testing.

But, I can definately tell you it is more interesting! (ducks for cover from all the freshwater tank enthusiasts)

I have found that all the fish seem to have their own personalities, there is alot more activity in the tank, it is more colourful. Just be careful it gets addictive....

a shop that sell marines.

do reefs set up do you need a lot of ligthing ??

now much water movement do i need for that size tank ??
