Salt Water Aquarium Lights

Despite all their potential and actual pitfalls, metal halides are here to stay. They do produce great quantities of lumens, and a gorgeous shimmering appearance underwater. Used properly by themselves or in concert with fluorescents they are the closest mimics to better-than-natural lighting for captive systems. My three gripes with metal halides are 1) their inherent costs, 2) safety, efficacy of use concer

I routinely have an air layer trapped in the top off these canisters and it takes a lot of effort to get it out. Granted, the filters will operate just fine with air inside because the manufacturer has located the return pump in the base of the filter (most others locate the pump on top). But, I still find it annoying to have the trapped air, and it makes the filter run a little noisier.

Second, the media containers are not as versat

Yay.

Bulb Life

For regular full-spectrum fluorescent lamps is @15,000 to 20,000 hours, but due to phase shift and lumen depreciation should be cycled out every year or so. They may still come "on" and look like new, but theyre not. With electronic ballasts, VO and VHO types can go nine to twelve months. Label all with an indelible marker on insertion and rotate out on a periodic (as opposed to all at once) basis.

Porcupine Puffer, anyone?

I'm planning on adding a porcupine puffer including 2 true clownfish in a 50 gallon FOWLR tank in the near future. I was wondering if anyone could give me good advice on the experience of keeping porcup. puffers. Thanks PS. I know porcupine puffers re.
