Submersible pump made water change simple

[dagray]

Just did my weekly water change and used a small pump. A game changer.

FREESEA 330 GPH 25W Submersible Water Pump for Pond Aquarium Hydroponics Fish Tank Fountain Waterfall https://a.co/d/eBP41zD

I use the Ehiem Universal 1262 water pump, output 900 GPH.

I used a smaller submersible recently and yes, much faster than a gravel vac. But I have a gravel substrate and need to vacuum at least every other WC.
I'm setting up a holding tank where I can then pump back in so I can graduate from 5 gallon buckets.
I'm still very new at all this and learning a lot. Can't remember the last time I learned so much about a new subject in such little time. Feel like I'm back in college. :-)
Sure appreciate the photos and seeing others' setups.

BTW, I just bought and tested 4 pumps for my son's all-in-one reef tank and I measured the output on all of them (as close to the pump as possible without restricting flow) and found them all highly overrated in terms of GPH, the results were all over the place with regard to stated volume vs. actual.

For water transfers, "enough" is good enough regardless of the stated GPH. But if you're curious, measure the output.

I'm lucky. I drain by gravity out to the woods. With my 1" ID hose and 1" PVC drain pipe it's fast.

I fill my storage barrel and circulate the well water for a few hours with a submersible ,300gph pump and then pump the water to the tank with the same pump.
The tank water is siphoned out the old fashion way[ patience required] into the waste water barrel which is pumped out to the out side into the woods with a 600 gph submersible.

I use a similar approach where the fish room is filled with double decker stands. The fish tanks are on the top so they're easy to see and easy to drain with a siphon. The lower deck has old, empty tanks I use for water conditioning and pumps to refill the top tank.

I just ordered a hyggar rated 400gph, as the python system is too slow. Also I have a sand substrate and clean it thorough once a week. Fun times

I drain out the dining room window into the yard

Occasionally drain into buckets to water plants.
