Started filling my 279g tank last night.
Right now it is about 1/4 full.

You can always upgrade to a higher GPD and produce a faster batch of water.
It all depends on your ro/di unit (GPD)-What is the psi on your ro di Gauage?
I just upgraded my RO unit from 150 GPD to 300 GPD by adding a second membrane. And let me tell you what a difference it makes. It used to take about 45-50 minutes just to fill a 5 gallon jug. Now it's down to about 20 min give or take. All in all it was a fairly cheap and easy upgrade too. Only cost about $35 for the membrane, housing and fitting kit off Amazon. Plumbing it in was easy, just ran the waste line from the first RO to the inlet of the second, then used a Y-fitting for the twin RO outlets before the DI stages. Now I can crank out roughly 12 to 13 gallons of RO/DI water per hour.
Most municipal water supply lines run at 50 psi +/- but even then a booster pump can be purchased for about $100 if it's needed. Also these days most RO units are fairly similar in design, many using the same housing layout. So as long as you match the same flow rate as your existing RO membrane you should be good to go with minimal expense.

It is 90GPD, pressure is 60psi. Once it fills before the weekend I am good. I have been looking at adding a second membrane, will most likely do it sooner rather than later no that I have a much bigger tank.It all depends on your ro/di unit (GPD)-What is the psi on your ro di Gauage?

Ok good.
Sine you have a larger tank now add a booster pump - it will save lots of money in a long term in terms of filters/waste water.
Mine runs at 100 PSI with a booster pump-
Did the same thing, added a booster, run it 80-90psi, and I can do about 340 gpd real time. Takes about 12-14 minutes to fill a five gallon bucket. I'm sure the math is off on that statement, but I timed it with a gradient cylinder once. It came up to about 340-360 gallons per day.
60 PSI will be fine for dual 90 GPD membranes. I'm running twin 150's on that psi level with no issues. Now if the pressure regularly dips below 45 then there will be issues with proper filtering and such, so it's something you would have to monitor and add a booster if it does. For me I usually just run my RO in the evenings after the wife and kids have gone to bed so there is nothing else that can pull the psi down.
I plan to get a booster pump in the not too distant future. There are other things I need to get before that.60 PSI is an acceptable range but not good long term for the life of the filters - plus takes much longer to produce water.
Imagine water coming out of regular water hose versus pressure washer hooked up to the water hose. Not sure if this is a good analogy.
