Looking for a pump that will pump water from my garage to my tank, approximate length is 100 feet with not much head pressure since I'll be pumping into my sump vs at the top of the tank. I'm brute trash can, so I have the option to drill it if the pump is external. Im not sure if they have a pump that drops in that will handle that distance. TIA.

I use the same model pump as I use in my frag tank so that if it goes down I have a spare already on hand. In my case, that's a mag18. It pumps from the basement to the first floor so probably 15 vertical and 20 horizontal feet. Although it's fast enough, sometimes it still takes longer than I'd like. I used 3/4" PVC for the entire run.
Not really sure on how fast, but not certainly to slow to pump water into the tank. So either 1/2 or 3/4" hose. Any recommendations on hose and pump is appreciated also.
Budget wise not really, but aiming for a pump that will suit my needs just to pump water.
BTW.. thanks for the help so far.
On that note, What approximate GPH would I need in this case for a horizontal feed of 100ft. with minimal head pressure.

Thats not a question that can be answered as you haven't defined the speed in which you want to pump water
Nor have you defined "minimal head pressure"...
With zero ft of vertical height change all you need to account for is some friction loss..
As a quick guess I'd equate 100ft of 3/4" ID horizontal tube to something like 5-7ft of head loss or so.. but again that depends on the flow rate through it..
Another quick guess is to get a pump rated to twice as fast or more as you want to pump it assuming you only have a few feet of true head loss.. Something like 5-700GPH should be plenty but you could certainly go higher... There are plenty of pumps that can handle that.. A cheap Jebao DC pump would allow adjust able flow rates,etc.... A Mag would be a submersible work horse.. A panworld would be a great external work horse,etc... Tons of choices..

Thanks mcgyvr. That's exactly what I meant respectfully, as you hit it right on the nail as far as what I was trying to explain. "As a quick guess I'd equate 100ft of 3/4" ID horizontal tube to something like 5-7ft of head loss or so.. but again that depends on the flow rate through it"..
So with that said. 5-700 gph will handle that distance but in actuality how long would it take to fill up say a 5 gallon bucket? What I want to avoid is a pump that going take 20 minutes to do so.
At 100ft, and given not including friction or head loss?
So say including head loss at both ends being at 5ft each, Id still be able to fill a bucket at around 5 minutes or so give or take?

5 minutes to fill 5 gallons = pump must do 1 GPM after all losses..
1GPM = 60GPH
Now you find a pump you like and then look at its flow chart.. See if it will do (at the very least) 60GPH with 10ft of head... If so... pump = "winner"
Why 10ft of head? Because thats "hopefully" plenty of overhead to cover your 100ft of hose and some vertical height change..
If that pump is ONLY rated to EXACTLY 60GPH at 10ft there is a chance that your 5 minutes for 5 gallon requirement won't be met..Just give plenty of overhead so find one that can do 100GPH or whatever at 10ft of head or more..
You can always put a valve on the hose to slow the flow down if your pump is "too fast".. But there is nothing you can do if its too slow.. So ensure its got more than 60GPH and all should be good assuming our 10ft assumption is valid enough..
1GPM = 60GPH

I would die of boredom if it took 5 minutes to fill a 5g bucket! :eek2:
I would really suggest a larger pump than you think you need. The upfront cost may be more, but time saved over the years of water changes will more than make up for that.
I control mine using a simple remote control outlet. I keep the control upstairs so that all I have to do is open the spigot in the wall behind the tank, turn it on, let it fill, close the spigot, and turn off the pump. I can do a 25g water change in about 10 minutes, and never lift a single bucket.

Im calculating 5 foot from my reservoir from my garage (pump submersed in container, then approx. 80-90 feet horizontally with a couple 80degree turns, then another 5ft up into the tank at most or sump at 2-3 feet.
So, with our convo so far what mag or jebao pump would meet my needs or more?
Me too, given I cant stay putt I gotta keep it moving. What pump and distance with head pressure are you using. And I definitely don't mind a larger pump and adding a ball valve to slow it down.

Im gonna bow out now...I think I've given you the knowledge to answer your own question.
