Fish Tank Hydroponics

My favorite was the use of an emersion coil looped within an old chest-type soda vending machine. Be very careful of contamination if you choose to "build your own".

Modern units come in two formats, either with a chilled coil you immerse in your system, or an external exchanger with a transfer fluid that the systems water is re-circulated through.

Whats that Latin saying? "Cave aquaristum", let the aquarist beware; there is a very wide range of quality, functionality and life-span amongst available units. By all means, compare warranties/guarantees, but do not purc

These systems call for chemical filtrants, more vigorous circulation/aeration, and other mechanisms to reduce water chemistry fluctuations.

Size:

Even though Im only 5 7", bigger is better (!) in aquarium sizing. Like ocean-size volumes, humungous tanks dont change much very quickly; in part because of dilution, and temperature -wise due to tank wall thickness.

Livestock:

What kinds of life youre keeping touches directly on the issue of the type of system filtrat

If "Brand B" does not perform quite as well, but is affordable, always in stock, is well supported by the manufacturer and can be sold for a respectable profit, many more retailers will choose to carry it. Remember that this is a business, first and foremost. If your store is run by a hobbyist and carries all of the latest high end equipment and is a hang out for all of the local a

They look similar to a large T fitting. Water is pumped up through the bottom and the water exits in an alternating pattern from each side.

Just like the Hydor Flo, these units reduce the water flow because they use that pressure to create the alternating pattern. Again, I dont feel like that is a major shortcoming. It is simply a tradeoff that one must make for the wave-like action. That said, I do think these units have one major weakness. They only come with barb fittings, and they are not very good barb fittings at that. I would much prefer if they came wi

3) Aspirate the! Just like an internal-combustion engine carburetor, a small/er diameter line (flexible or rigid tubing) can be inserted into the larger diameter overflow line/s allowing more gentle mixing of air with water... experiment with the length, placement of aspirators before affixing them permanently.

About Micro Bubble Problems:

A bunch of small bubbles in your water can be more than unsightly... they can cause serious health problems for your livestock. The best way to alleviate small bubble problems is to coalesce them at their source, usually the discharge side of overflow l

Complimentary Goldfish
I've heard of people traveling with dogs, cats, and even an occasional fish. But this Chicago hotel takes vacationing with pets to a new level. They will provide a goldfish....
