Aeration of Fish Tanks - Busch Vacuum Technology

A couple of different experiments to aerate my 2000 gallon fish tank, for aquaponics..

To address the plant issue: this may or may not be desirable for your tank; it's up to you to decide. The problem is the balance of oxygen and carbon dioxide. While the plants will provide oxygen, will it be enough for the number of fish and tank size? Some plants also don't live very well in oxygen-rich tanks. This would limit the amount of extra aeration (filters, decorations, etc) that you have. It may be easier to start with one of the other methods of oxygenating.

IMPORTANT! If you have more than one fish tank or end-use of aeration on your farm (such as multiple systems as we have), you need to have an air valve at each system to choke down the air and adjust air distribution so all systems are getting an equal amount of air. Why? When we installed our second system, we turned on the pumps and installed the last PVC fitting to connect it to the airline. The aeration in this second system was excellent! Then (luckily!) we went up the hill to feed the fish in our first system; and found there was NO air coming out of the airstones!

Aeration within your aquarium is very important for your Betta. Even though a fairly large fish tank with a chosen by a professional provides plenty of aeration, it’s still wise to add further equipment. To be cautious, many hobbyists install an airstone that connects to an air pump. This provides a stream of bubbles that are not only good for the fish, but also provide a pleasing site in your aquarium.Thus, when you set up your NPTs, look out for this problem during the first 8 weeks. You may or may not need aeration. This will depend on how deep the tank is, water surface area, amount/type of soil, etc. Let fish behavior guide you.Now, it is possible to have too many fish in a tank, planted or bare, and aeration might be required to keep them alive. That can be done in a NPT, too, but one should be aware that dong it will have a negative effect on plant growth.Too little aeration means your underwater friends don't get enough oxygen. If your fish are hanging out right at the surface, perhaps even gasping, your tank is under-aerated. It's especially telling when bottom-dwellers keep heading upstairs uncharacteristically. Your fishies might also spend an inordinate amount of time right around the filter, where water is being churned and aerated. In such cases, add an aerating device to your tank. The warmer your water the more aeration the ecosystem needs. If it's warmer than 80 degrees Fahrenheit, you almost always need something specifically designed to aerate. Overcrowding and medicating the tank can also reduce water's oxygenation.In my tanks, the water gets enough aeration just via water movement fromt the filters. I don't use airstones unless I see a fish problem or don't have a filter. Bubbling via air-stones will remove CO2 from the water, and CO2 is the limiting nutrient for plant growth in NPTs.I've never had a problem with low oxygen levels in a system except when the power has failed.. I find it a little strange when people are turning their fish tanks into spa baths with huge air pumps, when really they are not required unless you have extremely high stocking levels/hot water etc.. With such extreme aeration It means that you can't see your fish, and I'd rather see my fish at a glance to see their behaviour and their bodies, as these are your best means of knowing when there is a problem..
