Experimental Mini-System

I used this mini-system as a precursor so I would know what to expect when I got my 55 gallon tank in.

Oh! Another important lesson learned is to make sure the shelves upon which my system is sitting must be able to take on some water. I almost ruined my desk with a leaky tube because I didn't realize the varnish wasn't waterproof.

I blogged about my initial mini-system here:

The most important things I learned were:
- To be careful of the materials I use. Since the fish are an essential piece of the system, care needs to be taken to utilize food-safe and aquarium-grade materials where you can.
Examples: Miracle Gro's Perlite contains chemicals that could have made my fish seriously ill had I made this a live system. The caulk I used had an anti-microbial agent mixed in that would have made my fish ill as well.
Solutions: Hydroton was substituted (was going to use aquarium gravel and river rocks, but the Hydroton was cheaper) and aquarium-safe clear 100% silicone caulk is my new caulk of choice.

- Tubing is measured in 3 measurements: The Inside Diameter (ID), the Outside Diameter (OD), and length. Make sure your connectors match both the Inside AND Outside measurements.

- If you do decide to go with gravel, make sure it is a hard rock that leaves no dust when disturbed. When shaken, marble will create dust, even after the water runs clear.

Last, but not least:
- Grow lights are expensive and unnecessary. A daylight spectrum (about 6500 degree K) fluorescent light bulb in a desk lamp is all you need, and costs significantly less!
