I have a 25 gallon tank with a RES which is 7 inches long. I would soon be upgrading to a larger aquarium. Would the 106 be enough?I dont fill fully

I'm not sure, I bought the 306 for a 55 gallon tank and also have an older 305 for a 72 gallon tank.

Might be overkill for a tank that small. I believe Hydor makes a smaller version than the 425 that might be more suitable...

Yes. It may take up some space but it will fit. It is good to use a filter bigger than your tank size (ex: 15 gallon filter for a 10 gallon tank) if you have some thing in the tank that produces waste such as a turtle or fish.

If its a 65gallon long tank then you probably want the 900. If it's a 65gallon tall then you should be OK with the 425 if you place it in the middle

You'd have to look at the measurements of the tank. I got this for my 30 gal tank.

We use it in our 25 gallon tank and it works great although it is a little slow. However, this gives you more time to suction the more dirty parts of your aquarium. I think you will love it.

I would say the 700 or the 1200. The 700 is good for up to 65 gallons, so that would hopefully be enough for the turtle. I hear they are pretty messy though, so it wouldn't hurt to go with the 1200 which is good for up to 150 gallons. It seems like a lot, but you cant really have too much filtration. It would require less maintenance, keep the water crystal clear, and allow for you to use it for a larger aquarium if you decided to upgrade. It's totally up to you with your future plans and how much money you have at the moment.

I think the 306 would be perfect for a 40 gal tank. It has adjustable flow via a valve at the connections. I have a 206 on my 29 gal running full flow with community fish. Not excessive current. The flow rate is higher on the 306 by about 50%, but your tank is roughly 40% larger than mine. Plus it has more media capacity to increase filtration for those dirty cichlids.

I have a 75 gallon and run an eheim 2217 which is very large. I know a lot of folks will run two 2217 filters in a 75 or 90 gallon if they are heavily stocked. Eheims have great reputation if you search some of the forums from the hobby specific sites. I decided to not run the pro3 series because the classic 2217 can fit so much more biomedia for big tanks. I left the pro3 for my smaller 45 gallon tank. Check it out yourself and compare the flow rate and capacity before you choose the model.

I would always go larger than what I need. I have a 55 gallon with big oscars and I bought the xpl rated for 175 gallons. A bigger filter allows more water fitter action per minute and turtles are pretty dirty. My son has 4 turtles in a 45 gallon with a filtration platform plus a xp filter 4.

It was taller than my tank (about 20"). I had to send it back and get a smaller one for my 60 gallon.

I have the PF40, so I can't tell you anything about the PF25. I have had the PF40 on a 47G column tank and a 55G tank (barely fit the 55G). If you buy the filter rated for your tank size, it will fit. The PF25 is rated for aquariums up to 25 gallons. If you need it for a tank bigger than a 30 gallon, I'd buy a bigger filter size.

There is no problem in using a filter bigger than what you need. Every model has a limit, as long the model is for a bigger tank than you have is OK.

Depends what you are keeping. For a coral tank with few to none sps, 1 650 should be just fine, I'd start there. If you decide you need more, just add another later on.

The "float 125" on this ad indicates that it is good for up to 125 gallon size tanks. I think this is the one that I got for my 75 gal.

To answer your question truthfully... it all depends on your tank and what you're trying to do. You may be okay with a 500. This is my experience with the 750 pump on my 75 gallon heavily planted FW tank. I bought it when I had only one 55/75 aqueon filter because I wanted to circulate the water better. I think for my intended purpose, I bought TOO big of a pump because it kept uprooting my live plants despite it being placed close to the top of the tank and aimed up. I felt like the pump size I bought was too big and instead of buying a smaller size circulation pump, I opted to take it out and buy a second 55/75 aqueon filter. With two filters running, my tank has plenty of circulation so I don't feel like I need to add a circulation pump to my tank. Even though I don't use it in my tank(s), I feel it was a good purchase as I felt it was doing a good job of moving the water and it was quiet. Plus, I still use it occasionally to circulate the water in my bathtub while I'm curing big pieces of driftwood that I can't boil.

I have a similar turtle in a 30gal tank, and I use the 500 model. It keeps the water clear, but requires maintenance every few weeks. If you have the room and a few extra bucks, get the 700 model. The 1200 is overkill, but as the other person said you can't over-filter.
