Hello,

I've been researching rays for about a month now, I recently purchased a tank without filtration. I was wondering what would be more beneficial using a sump or two eheim canisters? What do you run for filtration (type, turn over rate, etc.)?

Any help would be appreciated.

Thanks
 
gshock, sump only or canister as well. I have a 110 and im scowering the tristate area for anything bigger than 150 incredibly hard to find around here
 
A sump will hold more media than any canister will. Sumps are best for ray tanks for many reasons.. first being that they have the ability to handle the bio-load of rays, which most canisters will stuggle with. And second, they hold all of your equipment, so there is no worry about the ray burning itself on a heater or breaking any of the equipment in the tank.

On my 284gal ray tank, i run a 50gal sump with a 20gal trickle tower in it. It has 20gals of bio balls in the tower, and 26 pounds of bio-max submerged in the sump.
I run it at 1600 gph... with two pumps.

I also run two fluval 405 canisters filled with more bio-max. I use these mainly as mechanical filters.

I also have a UV on this tank for clarity.
 
i dont have a ray tank, but i know from experience that over filtering always helps alot in the long run. Sumps are also very adaptable because you can change your media more easily and make your setup alot more ''custom"
 
My sump is 44inchesX24x24.

I aslo have large eheim for backup mechanical and some bio to cover cleaning of sump.

The sump and tank are plumbed directly to waste for automated water changes and I have a fresh water feed back to the tank for auto refil (filtered and dosing pump for dechlorinator)

Nitragon ion echange resin tube to take out any Nitrates (only periodic)

Sump is the way to go but I like having a cannister running alongside to cover cleaning regimes
 
Sumps offer simplicity and flexibility. Very, very little goes wrong with a well thought out sump. Items can be added or subtracted at your leisure. It can be drilled. It can be plugged. It can be moved. You can fill it to the brim or have it barely filled. Yu can customize the bejesus out of it. Sumps can be made to address any filtration issue be it mechanical, biological or chemical.

Having one, two or more canister filters included in your overall filtration is just icing on the cake!

I prefer sumps now that I switched from canisters (Eheim 2250 and 2026). I have a 210g with a 40g sump containing 5gal bio-balls and 12L Ehiem Pro. The filter pad media I use for mechanical is about three times more than I would have in all my canisters combined and with one return pump I still am able to more than double the turn-over for the tank. Plus, the Eheim 2026 now is used for water polishing as I am taking the filtered water in the sump and pumping it through the filter and through a UV sterilizer and back into the sump near the return intake. The 2026 is full of nothing but fine filter pads.
You will never get that flexability out of a canister....even if you had like 5....well maybe if you had 5....or 6.;)
