how do i make my 75g saltwater capable

[classklown90]

I have a 75 gallon freshwater aquarium that i plan on making saltwater someday soon. my only concern is how do i make it saltwater capable? i do not want to drill the tank so what are my other options? i also have a 20 gallon tank that i could maybe use as a sump(i have no idea ho that works either lol). thanks for the help

all you need to make it capable for salt water is to add salt to the water. sumps, skimmers, and such are just added measures to make your life easier.

are there any HOB filters and/or skimmers that i can add to make life easier?

 

[mr_X]

yes. as a matter of fact you can add a HOB skimmer like this one-
Reef Octopus Hang on Back Protein Skimmer BH-300
(it's always a good practice to buy your skimmer rated for 1.5-2 x your water volume).

with that skimmer and lets say about 80-100lbs of live rock, how often and large would the water changes need to be?

 

[mr_X]

that would depend on the bio load and your feeding. i would be very comfortable with bi-weekly 15% changes, but again, it depends.
you are talking salt water, not reef, correct?

 

[classklown90]

actually i planned on corals once the tank was up and running a bit

 

[mr_X]

corals need much better water than fish for the most part. i would do 20% weekly water changes with a reef grade salt, to keep good water parameters and also replenish trace elements and calcium, and you should be fine.
