Fish Piranha Tank

Unfortunately nitrites are also quite toxic to animal life, but again, we are lucky that another set of beneficial microbes exist that readily convert nitrites to nitrates ("nigh" "traits"). As it turns out, accumulated nitrates are not nearly as toxic to marine (or freshwater, brackish) life as their precursor molecules. A good value to aim for is to try and keep your nitrates below 10 ppm, but fishes especially (compared with many invertebrates)

Some of these units are plain garbage, not "pulling down" anywhere near what their manufacturers claim, leaking, failing, going to fish-heaven in less than a year. There are reputable people in the trade, and a few more units on their way, thank goodness, that will hopefully oust the charlatans.

Placement of chillers is critical; they should be where you can reach them for cleaning and checking, but also positioned for thorough ventilation and no water contact/splashing.

Doing

will enter your system (mainly through the air). By using some, a mix, or all the methods mentioned above for introducing and boosting beneficial bacterial growth, you will realize a progression, growth of bacterial populations that will result in an increase at first of ammonia, then compounds called nitrites (made by bacteria converting, adding oxygen to ammonia), then in turn nitrates (made from further adding oxygen to the nitrites by another group of bacteria). This process of converting ammonia to nitrite to nitrate is termed nitrification. It is the principal way aquari

I went to remove and clean it again, when it broke coming off. It then went into the trash, and that was the last time I used anything with the Rio name on it, having had several bad experiences with their powerheads as well. For more information:

It is a good idea on paper, and is very similar in operation to those old-style rotating spray bars that came with the first wet/dry filters. These would routinely clog as well and

Large Power Filters: Before the invention of the undergravel filter, people used large, bulky power filters to cultivate beneficial bacteria. These original power filters were gigantic, compared to the modern hang-on power filter. Some were as large as twenty four inches across, and held up to a gallon or two of water and filter media. They used glass filter wool as the media to cultivate bacteria, which was usually layered with charcoal (We didn

250W HQI (Double Ended) MH Retrofit Reflectors
I just got these in! I've been waiting to see them. They are very nice well built reflectors. Not flimsy at all. Vented, and they include a nice heavy glass shield. They are available in a 150w version also if there is interest? I dont have too many right now-I wanted to get a look at them....

Angel Fish Pterophyllum altum (back) & scalare (front)

After keeping and breeding Angel fish for a couple of years I decided to replace them for a group of discus fish, that was about 10 years ago. At that time the beautiful Altum Ang.

DIY- Converting my stand into a sump!
I started a new project over the weekend. I thought it was a pretty good idea, so I thought I would share. I have a 120 gallon reef tank. Mostly zoas, a few lps and a few sps. The problem is I have very little space for new corals. Probably my favorite part of the hobby is fragging and growing new....
