WP10 or WP25 on standard 29g?

I have some Amazon credits so it'll have to be one of these.

I'm worried WP10 won't be enough flow on its own. Should I get the WP25 instead? I like that it has night mode.

If you are only getting one get the WP25. 2 WP10's are being used in my 29, but I think that 25's would be better.

Well I got the 25 today and it isn't going to work. It is nothing but an extreme sandstorm in my tank on every setting, even the lowest.

So do I get 2 10s or do I get something else that is $100 or less in total?
