I don't understand how trickle filters work, nor wet drys. Could someone explain how these function? I have neevr seen one before either. Curiosity got the better of me.

i dont remember trickle filters... but wet dry, i think thats basically when the water is filtered by meeting with air or sumin like that. like the bio-wheels, the water come in contact with fresh air, so its wet-dry, but im not sure if a bio-wheel is really what a wet-dry filter is exactly...

A trickle filter is when you let water come out of your tank into a waterproof box. The water trickles over these balls called bio-balls. Then at the bottom of the box, the water collects. You place a pump at the boxes bottom and pump the oxygen charged water back into the tank. You can place filters over the balls to mechanically filter the water too. Basically wet dry is exactly the same. Wet dry by definition means that the filter media is not submerged under water, but exposed to both air and water, by trickling water over it.
Remember... Mechanical is filter floss, Biological is bio wheel or oxygen working on a media, Chemical is carbon or zeolite working on keeping ammonia level down... You can have all three in any filter system you like.
Hope that helps.
