or this one? i need help

Well if you're getting a 90 gallon then neither of those will work. You want a filter that can handle at least twice the load of the tank. Also GPH rated at 5x an hour of what the aquarium holds.

The first one looks extremely generic. I would highly highly doubt with a full load of media that it would do 369 gph or even half that.

The second one looks like an extremely cheap knockoff of the Fluval 404/405.

My question to you about both. If something needed to be replaced, where would you get replacement parts?

ok yea i have never purchased a tank more than 55gal so i feel like this is all new ive been reading i like the one you put up it seem technically good sooo thank you if u have anything else to say about anything you think i should know please feel free to put up links or write a novel thank you for your help im going to go read some more =)

Mo-grape - Keep in mind about the 5x rule. You want a filter pump to pump at least 5 times the volume per hour (gph) Watch out for any comparison to fish tank sizing. Double this? or Triple that? means nothing when comparing turtles to fish. Turtles doo a lot more that fish and require more and different filtering. b.

With canister filters, you get what you pay for. Buy a name brand like Fluval, Rena, or Eheim. You will spend more money, but you will get a reliable filter that you can easily find replacment parts for if something breaks.

My first canister filter was a Fluval 304, for a 55g tropical fish tank. When my boyfriend and I got a second 55g fish tank, he decided to get a cheaper filter. He got a Penn Plax canister filter, which was half the price of a Fluval. Yes, Penn Plax IS a name brand, but it was a cheap filter and it was a piece of junk. We had nothing but problems with it, and finally my boyfriend just went out and bought another Fluval to replace it.

ok im still looking ive just never owned a canister b4 im still reading thank you all for helping now im feeling better on buying a 150-200$ filter ayyyy but not too much better but ive had my turt in a 20g a little too long shes almost 4 inches so shes going to be sooooo happy im going to look at the diy filter stickey too .

I hear ya! I was in the same boat as you. Heck if you look at only a few months ago I was looking at generic filters just like you. Now I've got a Fluval 404 and a Rena XP4. I'm so happy I bought name brand.

ok ill go with a name brand thank you all for your help this is just all so new thank you for your help my fellow turtle lovers =)
