you guys think a K nano is good enought to stir 15 gal of salt water?

I have a 29 gal BC that i do 20% water changes every week.

I don't have time to run to the fish store every week for when I do water changes, so I have 15 gal of salt water in a rubber-maid container with a k nano power head and a heater. I choose the k nano because it runs 240 gph and runs off of 4.5 watts. dollar cost wise for running 24 hours this is the best choice.

Do you guys think that this nano (240 gph) is enough to keep the water turned? keep in mind every 2-3 days the water level will drop by 5 gal per week until i get more water and this is in a rubber maid container with nothing else in it.

I don't want the water to turn stagnate. thats all, but i also dont want to spend the extra money for a bigger pump that also runs more watts like the rio 1100 + that runs 22 watts and turns 382gph.

for this application is there a really a big difference between 240 GPH and 382 GPH?

Koralia Nano's are pretty weak in my opinion. I mean, I think they're great for 10g tanks and under. But I can't imagine it being enough to keep 15g of water turned.

20% changes every week may be overkill given what you have in there (if your sig is accurate) . I would just do bi-monthly 20% (or 30% if you prefer) changes, that way you don't have to have water sitting around.

But if you want to keep on the weekly schedule, that pump way more than enough. I use a crappy old minijet 404 to mix my saltwater in a 5g jug and that's only like 40gph. Even then you only need to run it the night before a change to aerate the water so that the pH isn't too low.

It's way more than enough. I've used the same set up. Mix the NSW up very well by hand and then turn the K-N on. As long as the surface of the NSW is moving, you are money.

good to hear, as the k nano cost .64 a month to run vs $5-7 a month that the pump my LFS recommendend. The pump also costs $20 more and runs 35 watts

4.5 w/1000=.0045(KWH)*24(hours)=.108 (KWH a day) * 30 = 3.24 (watts per month) * .20 (cost of my electricity per KWH) = .65

I like the sound of .65 a month to run this powerhead.
