Yup, screwes into the wall for sure. AK, the only downside is a big one; if you dose too much ozone you can nuke your tank, destroy your skimmer, and damage your own lungs . Ok those are worst-case scenarios, but Ozone is a POWERFUL oxidizer. The above worst-case examples are really only ever found by people who don't understand the potential of Ozone and don't know what they're doing. if you take your time, figure out what and how Ozone does, you'll be fine . Benefits are cleaner water, removing any pigments in it, and increased skimmate potential.

Huh, yeah imbalanced impellers is not a common problem... Did you take the impeller out to look for stuff stuck in/around the magnet? Might just be a bit of sand stuck in there.

Yeah I've stripped everything down and cleaned it however I'm still experiencing the same problem. I'll hopefully get a replacement soon.

AK do you not live in somerset? or is that just the impression I got?

Nope I hail from Kent.

Tank looks great! Where did you get the MH's from btw? They look just about pefect for what I had in mind (from the looks of it they clip on the back of the tank?)

I got the MH from Ebay. If you just type "Metal Halide" into the search you should see some identical ones to mine but in black. I think they are about £40 a pop but are well worth it as they contain the ballast, capacitor and ignitor. All you need to do then is get either a 10k, 14k or 20k DE (Double Ended) bulb. If you get some 3 core flex from wickes and some in-line cord switches (Maplin) and just wire them up, you are good to go. Mine are bolted to the wall with some M8 coach bolts.

Ski thanks for the heads up. I'll definitely have to inquire into it all. Do you have any shots of yours? Is it like an O-zone unit or an aerosol or something?

Thanks chaps!

Actually it looks like a small plastic electrical instrument box. On the front there's a dial to control the amount of Ozone produced, and there's tube fittings and a powerchord. Inside is an exceptionally high voltage A/C transformer, a few basic electronics, and some enclosed tubing. If what I know about Ozone production is true, the transformer steps-up the voltage to probably the tens of thousands and places the potential on either sides of the tubing. The high electric potential causes Oxygen from the air moving through the tube to oxidize itself and then form Ozone.

There is a dryer unit that comes with it which is a tube full of beads that takes the mouisture out of the input air. These beads change color when they are spent and need to be changed. They are rechargable via a quick trip into an oven, or in my case a little toaster oven for energy efficiency. My guess is that should water come in contact with the high electric potential, it would be electrolyzed and split into hydrogen and oxygen. A mixture which might be a tad volatile

I wouldn't worry about the voltage though, as there is only potential, not current flow. My best analogy would be a Van de Graff Generator that produces Ozone.

Most models require a small air pump to work. I used the smallest one I could fine and encased it in some socks to keep it quiet

Hi Ski,

What are the like for power consumption?? Are there any recommended manufacturers/models?

 

[SkiFletch]

Very low on the power consumption. Mercifully AC to AC transformers are very efficient and waste little energy as heat. I'd be surprised if my 50mg/day unit uses more than 30watts of power.

Most ozonizers are good quality and reliable. I personally use the Red Sea version, their smallest unit (50mg). About the only ozonizer I've heard conflicting reports on is the Coralife one. Some people complain that it fails often (fails OFF, not on), others are happy with it... My RedSea one's been going for about 6 months so far
