I have a lot of experience with keeping freshwater/brackish fish, but don’t have the money to buy a huge 120 gal tank for any large saltwater fish.. so then i discovered nano tanks, im pretty sure i would be able to handle something like this but i need to know how much they cost to set up
I plan on getting a 10 gal tank for the set up any advise on a nice brand for someone on a budget?

Any one with nano experience please help/ give advise, detailed answers would be appreciated :]

I want to start a nano reef tank. Probably something in a 3Gallon tank that I can leave on my desk. A couple corals and maybe 1 or 2 tiny fish with some sand. But some things come into play as to whether or not I can start one.

1)I am complete NEWBY to saltwater setups. (I am willing to learn)
Can beginners maintain a nano reef tank? Are they more difficult to keep that bigger reef tanks?
2)I have a 150$ budget. That I cannot pass. Maybe I should buy a nano tank KIT.
Will i need expensive lighting(the light that comes with a kit is good enough?) and a water cooler for summer if I live in California?
3)I do not want to change the tank’s water every single week. (Every 2-3 weeks is fine)
Does a nano tank require more weekly maintenance than bigger tanks because of the smaller filter?

I know this is a lot to answer, but I would like to know these answers before I decide to spend my time doing research on saltwater setups.
I was thinking of getting something like this.
