Salt Water Fish Aquarium

Some anaerobic denitrification does occur in every system; but not enough to offset the forward accumulation of nitrate. There are filter module products that portend to promote these microbes and their beneficial activities. Like dating, I urge you to be careful in their selection and use. Many (dates and denitrators) are "high-maintenance" units requiring daily fooling-with. All have the potential defect of other anaerobic production toxifying your system. Finally, in my opinion, theyre just not worth the hassle, c

Well "Henry" decided that we would place the custom undergravel plates and gravel (2,000 pounds of washed #5 coral shell) into the tank without the above-proscribed test-fill. I can hear him now, "Oh Bob, dont worry, I tightened those plastic through hulls (in the bottom leading to and from the remoted filtration) just a smidgen with the channel-locks". Now, Dear Reader, you and I know better than to put a tool to a "hand-tighten only" fixture, a

To retain the structural integrity of the tank, and to provide for "welling" up of the water ahead of its flowing back and over the down spouts. If you find your overflows are so large that theyre draining too much water to allow for the water level height, or have so much water in play that your sump volume is being overwhelmed with the power turned off, you can add "street" elbows that you can "turn up" or on their side/at an angle to adjust water height and transit volume.

This prefilter design greatly reduces the chances of the siphon action breaking, either from collected air or when the filter pump stops.

Wet-Dry Filters: Wet-dry filters are typically rectangular acrylic or glass reservoirs that sit below the aquarium. Most are divided into two basic sections, the "wet-dry" chamber and the "sump." Some wet-dry filter models may also have additional sections or chambers for in-sump protein skimmers, de-nitrification systems, canister filters or for pre-filtration of the water.

The wet-dry chamber houses the biolo

In reverse flow, a pre-filtered powerhead pumps water down the lift tube and under the filter plate where it can radiate up through the gravel bed. Reverse flow undergravel filters are just as biologically efficient as conventional ones, but some aquarists believe that the substrate is kept cleaner because the flow of water is constantly lifting dirt off of the gravel and up into th

Scratched Glass
Most of us have run into this problem at one time or another. Care to share your experience with scratched glass? "Does any one know how to fill some scratches....

vermetid snails, putting them to good use. :)
i have alot of vermetid snails in my aquarium. until an hour ago, i deemed them to be a usless,ugly and very messy. turns out i was wrong, they still are ugly and messy, but certainly not useless. i have 2 snails very close together on a huge gsp rock.
