Saw a lot of drip systems recently and saw how its making everyone's life easier so I decided to throw one in myself. I decided to go with a very cheap system because I figured the simpler the design the cheaper and it would (hopefully) be more reliable. To start I have a 125 with 5 Piranha and one Giant Danio. Before I go into the details here's the parts breakdown:
Eshopps Overflow Box PF-800: $70
Saddle Valve: $5
25 Feet of refrigerator line: $10
In-line fridge filter: $30
Grand total: $115
The filter I bought was to filter out chlorine which luckily for me is all that my water supply has. I bought one that lasts for 5 years or can filter 7500 gallons of water. On to the pics.

Simple saddle valve tapped into the cold water hose line outside.

Lines going inside. I'll make this look better later. For now I'm just getting it set up.

The fridge filter. By my math it should last two years non stop if I only change half a gallon of water per hour. I'll probably make this look a little nicer in the future as well.

The overflow. I seriously could have saved costs here and made my own PVC overflow but I've fooled around with those in the past and I just wanted something reliable that I wouldn't have adjust a million times.

I did a estimate here and it came to roughly .5 gallons per hour or about 84 gallons a week. I figured that's more than enough. I didn't want to use a dripper because I was afraid of it clogging.

Here's a full tank shot. I'll admit they are literally in nothing but a glass box with water but I like it and as far as maintenance goes I haven't found a way to make it easier than this. I guess I just like enjoying nothing but the fish. Not to mention I'm awful at aquascaping.

Final close up shot. They are roughly 8 inches each give or take a little. The only other filtration aside from the drip system is a XP4 which does the job nicely. Currently Nitrate is at 20 PPM. I'll let the setup run for a bit and I'll post an updated nitrate reading in a week or so.
