Hailea Ozonizer Model HLO-800

First Looks
Got the unit last nite and many thanks to Bro Bonjour2 who took the trouble of getting the units to me. The packaging is far much better than the Enaly and the unit is protected with a fuse. In addition, it comes with a 3 pin-plug connector unlike others using a 2 pin power plug connection. Another safety feature from Hailea. ;) Also, the manual is bi-lingual (English and Chinese) and the package comes with a Hailea Model 9902 Air-Pump too :p The finishing of the product is excellent and the whole unit is supported by four flexible rubberish legs which provides a very firm support to absorb any external vibrations. The unit has 2 outlets (not plastic) which looks like titanium or steel and they are distinctively indicated as input or output . So more more guessing which is which :p It has a variable control knob to adjust the ozone output which is important for first-time-used aquarium so that livestocks and corals can adapt slowly to the "clear" water condition instead of getting a sudden blast of "brightness". ;) Working It Like other Ozonizer, it is best to use activated carbon to remove any leakage of O3 back to the main tank. Before firing up the unit, the outlet of the ozonizer is connected to the venturi input of the Macro Needle Wheel Protein Skimmer via air tube with the input from the Hailea air-pump outlet. Holding my breath, I powered the fella and would expect to detect ozone but couldn't smell any after 30 minutes. It may be too early at this stage to conclude due to "running-in" of the unit as the variable knob is set at 10 mg instead of the optinum level of 50 mg. Time will tell but at initially findings are very encouraging ... will check tonite again. :D Last Say Initially I am not expecting too much from this product after the experience with Enaly but what a surprise! :D The only feature which I don't like is the large footprint of the unit which occupies 5.5"x7.5"x2.5" nut if you need a versatile unit with small footprint, take a look at the Sander or Aqua Medic Ozonizer which costs many times more. So instead of comparing apple (China-made) with Orange (German-made) which is on the wrong footing, the right approach is between China-made apple (Hailea) and apple (Enaly) and my vote go to Hailea. My last say is that this Ozonizer is a great product and good value for money if you need an inexpensive ozonier to get rid of pathogene germs and dissolve harmful chemical ingredient as well as organic matters in water including illness treatment for fishes. Once again, I would like to reitierate that I am only an aquarist and are writing this review in my personal capacity to share my views to fellow reefers. Also I do not have any invested interest in any commercial products (dry food, equipment, etc) relating to aquarium fish keeping. |

Connecting the unit with another Hailea Air-pump Model 9602 sitting on top of the ozonizer ..

With the ozone output set at 10 mg initially with gradual increase over the weeks, the ozone is fed directly to the venturi input of the Macro Needle Wheel Protein Skimmer ...

And this is the outcome of the skimmer before applying ozone 10 hours ago ....
Stay tuned for updates ... |

No mention bro , I happen to want to check out yr sanders connection.. and compare both footprint ....collect cyclopeeze :( .so small matter that i send it to yr doorstep..muz state this or else other reefers think i biase y theirs no delivery.. ;) Gd review there. |

Yes .. Macro Skimmers are ozone complaince even for those 1st generation type ;)
|
Can we not hook up the airpump to this O3 maker? Just let the Ozonizer suck in air itself, can?
|
You can connect the ozone output directly to the skimmer and let the unit "sucks" the air but it will get clogs with dust up over time thus hampering the efficiency of the unit.
Using the airpump to deliver "clean and dry" air to the ozone is a better approach to ensure the ozonizer is working near to its max efficiency level. |
thanks for the effort to do such a detailed review here. ;) anyway, r u using ozone safe tubing ? heard gotta use silicone type or something :(
|
Aiyah . don't give me that compliement lah as I just want to share my views to reefers who are using or intend to get the Hailea Ozonizer. :D
Yes .. I am using the ozone safe air tubing ie silicone type. ;) |
i heard the only place that sells the ozone free tubing is petmart ? where do u bought yours :p

How many toys u wana buy Ken? U not young anymore.:p
|
me always enjoy reading ken's product review ;) at least i have the idea how the product works before i commit to it :p
|
Well written report, Ken... Thanks.
The picture shown that both the ozone unit and air pump are using a 3-pin plug. This is a "+" point and I think this is one of the rare 20 Air-pump unit with factory assembled 3-pin plug. ;) in Singapore. IMO, the unit looks "professional" as compare to Enaly. If only both the "IN" and "OUT" shift to the front, the design will be near perfect !! Ken, please update the progress in 10-days time :p . (I will only install it this weekend due to suddenly "heavy" work-load and I am oversea by the time you read this msg :o ) |
Ken , maybe you can explain some connections sequence for the reefers who bought the ozone generators as I realise that quite a no of reefers who bulk order are not familiar with hooking up the ozone in situations like;
1) If no sump tank, how to hook up? 2) If Skimmer is not ozone safe, where to discharge ozone to? 3) What is the proper connection , ie , where the tubes goes to where? 4) What is the recommended settings for different tank size, 5) and the duration of ozone discharge if running w/o a ORP controller. Will you be kind enough to provide the reefers out there with the a/m FAQs. ? Appreciated. |

Hi Ken,
After so many review on ozonizer of different brands. I really hope to see a comparison chart soon something like those for the computer hardware. Then we can have a showdown of all the brands. Cheers. A review well done. Keep up the good work. :OFF TOPIC: Really hope that I can catch up with you more during the AquaRama 2005 but I'm with a friend so I couldn't stay and chat. So when is the next ba chow mee session? |

Can I ask you guys how to make the air dry ? I am using silica gel seal up in a 500ml bottle & air go through it but it all turn pink within a week, any other media that can i use which can last longer ?
|
Quote:
The air is still not dry. BTW is there an internal check valve in this ozonizer? Otherwise why would the in/out matters? |

Air dryness i no comment..unless i got humidity meter to check. yr 3rd comment even more cute, i don think anyone will know how to ans u, only the manufacturer knows, cos it is stated clearly on the cover; "there is high power voltage inside , do not take it down at random unless u r the repairing worker. " so perhaps u can consult Hailea and ask them this? or i can pass a spare to u to experiment plugging in the air flow reverse manner and see the outcome? :confused: |
Quote:
Anyway, if u r dropping it into the sump, be careful not to let the ozone accumulate in the bioballs or ceramic rings area or all yr aerobic bac is bye bye, imho. Also, do take caution not to let ozone discharge get suck by yr return pump back into main tank... ( not my advice but from some manuafacturer's site) . use carbon after the ozone part . as a safety precaution... ;) |

I'm just curious if there is an extra safety feature in this unit (to prevent water backflow) stated in the manual. Thats why the direction is important. Anyway humidity in singapore definatly very high don't really need to measure. |
Let me try to answer inline to your questions:

For ba chow mee .. anytime. ;) Quote:

Most of us usually install the unit over the water level where it is well ventilated and also to avoid water backflow - just like the Enaly which recommends installation above water level. :D If really so kiasu then get a check-valve lor like yours truly for my two Sander Ozonizers ;) Enaly Ozonizer .. detected ozone leakage immediately after powering on :eek: and the rest was history for my Enaly. |
Quote:
Agree, humidity in spore is high. imo , the in / out is a reassurance to the consumers how to plug the airline, trust me , some consumers have sleepless nights if no one can confirm their installation. But imo, u have a very interesting thought there,tis shows tat u r extraordinary... r u in engineering? :p |

My only concern is that it is lasting or not. It may take a few months before some rubber/plastic inside get eaten up by ozone. This is the feedback I get from some people about thoese cheap china made ozonizer. nim75sg you should let us know in a few months the progress of the unit. I was contemplating on getting a sanders when the enaly bulk order came up. The reviews in RC (both long and short term usage) seems good and its appears to be fairly lasting. BTW Does this unit comes with the hailea air pump? |

"do take caution not to let ozone discharge get suck by yr return pump back into main tank..." not sure, does it mean, put the air stone far far way fr the return pump? |
