What would a proper flow rate,(gph), be to move water in a 75 gallon saltwater tank? Just to create a current.
 
Depends on the type of critters you are looking to keep. 10 to 11 turnover is the standard from the sump. I prefer MUCH, MUCH higher, 50-70 x the tank volume for circulation within the DT since I have primarily SPS.
 
I dont have a sump.
Canister filter and just need good current flow.
How many gph would work?
 
Would 1500gph be too little?
How about 3000gph?
More, Less ??
 
Again, what are you looking to keep? LPS, softie, SPS, mixed with what predominantly?

I am new to this and don't know your abbreviations.
For now fish.
Eventually coral but don't know what kind yet.
 
At this point, I wouldn't worry about the flow in the display tank beyond your circulation. When you make a decision to get corals then cross that bridge. Don't spend more money than you have to at any given point unless you are certain of what type of reef system you plan on keeping. Lord knows this hobby is not cheap.

To help with abbreviations, please see this. It will help to better understand the language of the marine aquarist. I find it helpful all the time.

So the fish don't need a current or water movement ??
 
A couple of these should work. You can turn up or down depending on your needs you can get cheaper but no control over output

That should be fine for fish only. When you do add corals, I strongly advocate ditching the canister filter and set up a sump system for best coral health.
 
I to agree to lose the canister when you start with corals they filter nicely but they are a great nitrate maker . You don’t nessicaraly need a sump .

Why won't the canister be sufficient.
Will the coral still live.

So 132-1056 gph on each side of tank.

I have read bad reviews about those stop working after 3 months to a year.

Dont want to waste money.

Canister filters can have a place in reefing. Don't get me wrong. The canister filter provides mechanical filtration via the sponges, biological filtration via, usually, ceramics of some sort, and chemical filtration via media bags placed in situ. Your biological filtration is or should be supplied primarily by your live rock and sand. So, no real need for that within the canister. The issues arise with the level of work a canister filter poses. As a reefer, your success will be dependent on how good your husbandry is. The canister filter needs regular, at a minimum every 2 weeks, cleaning for a reef tank. The sponges get clogged rather quickly and need regular swapping/cleaning or they become nitrate sinks. We are trying to keep corals and the vast majority of them prefer low nitrate environments. Taking a canister filter offline and cleaning it regularly to maintain a healthy reef tank can become a chore in no time and a lot easier to neglect or let slide. As this is more likely to happen the demise of your reef is more likely to happen. Ditch the sponges and you have a glorified media reactor which is a good thing but still requires maintenance. You can get away with keeping the canister filter as is but you are making more work for yourself and potentially turning you off the hobby or skipping a cleaning and your corals suffer which in turn causes more work and turns you off to the hobby. I am of the opinion that we should try and make the 'work' of keeping a successful reef aquarium less work so that we can generally be more successful. If I were in your situation I would keep the canister filter as a media reactor and find a way to install a sump so that I can have a protein skimmer and have less work. Also, I would stick to easy to keep softies and some LPS corals and zoas & mushrooms. Keep and us the canister filter however you deem appropriate but be aware that your work, in my opinion, will be significantly greater if you choose this as your only means of filtration in a tank of that size. It can and has been done, of that there is no doubt. You will have to up your husbandry game though and there is less room for error. Try to make life easier with less maintenance or maintenance less of a chore with fewer problems arising and reefing becomes more successful and enjoyable.

How do you turn a canister into a reactor and what setup do you suggest for a sump.

Remove the sponges and bio media and you have a self-powered reactor. Simple as that. There is a myriad of ways of installing a sump. This will depend on your DIY skill level. The easiest method is to install an overflow box but that requires drilling the glass. Some glass cannot be drilled if it is tempered. Give this video a view and that should help immensely.
