Im purchasing a new 20gallon tank. I only have a filter rated at 5-15gallons. Is this going to be enough or do i have to get another one? the reason i ask is the lower the price the better. thanks!
It would be best to get an updated filter with the updated tank. I always buy filters rated for MORE than what i'm actually using them for, & that way in an instance like this one with you, i wont have to buy another one
Have you tried looking on Craigslist for a used tank, they usually come with all of the accessories and cheap. I personally would not use a filter rated for the size of my tank (I always go for more than needed) ie, if you had a 10 gal tank than the filter you are mentioning would be fine but for a 20 gal you need something bigger.
