hello, I just picked up a 300 gallon tank for a relatively good price and after looking through all my filtration options, it is looking like a sump is the most effective/low maintenance/cost efficient filtration for a tank this size. problem is, I have absolutely NO IDEA how to set a sump up, or if it's even possible on a tank that's not drilled.
I have a ton of questions and was really hoping someone could point me in the right direction on a thread about setting up a sump for first timers or maybe suggest premade sumps?
 
I would suggest a pond/sand filter. They are effectively no maintenance. With the backwash option you clean the filter as you drain the tank for a water change, that's it. After using them at the shop I was running they are by far the way to go. Easiest and most effective. It is the filtration I will use on my dream tank.
 
^^^interesting

I would vote for a sump. What are the dimensions of your tank?8x2x30"? That I believe is the most common. What parts do you have? Are you a DIY er?
 
Since your tanks not drilled just get over flow boxes w dual outlets. You could plumb all the rest up using PVC from lowes or home depot.
 
the pond filters I have looked at all have external pumps that need to be in your tank. otherwise I would have gone that route.

yup common dimensions on the tank
what do you mean by "parts" I assume I have nothing
and I'm sure once I read how to properly set one of these up I shouldn't have an issue.
 
If it isn't setup yet and you do a sump, just drill it. It will work much better.

You could use a tank for a sump to house the pump and run the pond filter from there. You could use an acrylic sump and drill the side for an external pump and do the same.
 
As in parts i mean any PVC or overflow boxes pumps etc. Flow inside the tank will be important too due to it's length. Simple way would be to get overflow boxes PVC and a 75g junk tank that holds water for use a sump.

Here's some things to research (because it seems when I learned how to do sumps I had to check everything out on my own)

- pump size including head rating
- flowrate (turnover rate on larger tanks is not as easy as smaller tanks)
- sump size (you need enough room to hold your media/equipment and all the water that will drain back in the tank while power is out or pump is not running)
- drain size and flow capabilities(your drains will dictate your max pump size or you'll overflow your tank)
 
I was wondering if someone could inform me on the drip tray part of a wet/dry sump. Specifically, weather having a pump that pumps 2500 gph would move water faster than the drip tray could pass. Is 2500 gph too much?
