The ULTIMATE UV Steriliser! Deltec 10w & 48w UV Review

[@TimChump]

Love the reality of braking the bulb 😂❤

[@rudra7615]

UV changed the game for me after I had my first ich breakout. I went for the TMC uv vecton titan and really like it and use it on my Red Sea 170. Able to fit it inside the bottom cabinet.

I love these review videos!

Fellow quartz sleeve breaker numpty here 🙋‍♂️ 😅

👊

[@lovermansmith9082]

Cool ! I was impressed with the price of the sicce ❤

[@vascojardim6703]

The quartz bulb allows about twice the amount of the radiation to pass through vs normal glass bulbs. Hence Deltec’s claim for 2x the power. It also makes the bulbs 2x as expensive.

If you go on the DD website it lists flow rates for a reef tank and a fish only tank. The fish only tank gives you a slower flow rate. Im guessing thats for parasite control. In the case of the DD 10w UV the minimum flow rate is 230LPH and for the 39 watt its 920LPH minimum

Hi @Reef Dork, Good vid and info, thanks (& sorry about the quartz sleeve!). Quartz sleeves are a pain, and were always being broken in the large wattage units used for ponds where I used to work...and they ran to nearly £100 for a replacement (~25 years ago). Maybe the difference in unit length is if they use different bulb types, e.g. your 10w looks to have a "double tube"/side-by-side one, but perhaps the 30w has a "normal" fluorescent-style tube? Cheers, Rich.

[@Wissperwind]

cool that you use metric units in the thumbnail picture. one advise: just use cm not cms even if it is longer than one cm

[@GazzasReef]

Vecton Titan for the win

[@gap9992]

I have the 48 plus a small DC pump but I have not got round to installing it yet! I had not thought of putting it in the sump but it makes perfect sense and will spur me on to getting it fitted! Unfortunately my sump is just a little too shallow to use your bracket. Any chance you could make a version to fit the slightly larger centre tube section with the flange sitting on top of the bracket??

[@ReefDorkXtra]

There are too many potentially niche options people would ask me to make so I'm just gonna go with a one size option I'm afraid...

[@The1NdNly]

I've just picked up the 48w for my system. I believe the flowrate is what they rate the unit for at 33,000 microwatt's/sec/sq.cm. off the top of my head (its gone midnight) i think you need 300k for parasites so 10x slower than its rated for.

[@ricotter9233]

@@The1NdNly thats too slow and the bulb will overheat. Algae is 33000 which if you run the unit at its suggested rate it will be efficent. For marine ich sterilization (not too kill as these uv units are not powerfull enough to do) is 72000 so you need to slow the units recomended flow rate down by 2.18 too acheive that. I personally slow it down by a third to hit 99000 and this then covers me for the bulb losing intensity over the year.

[@scottwells1692]

They say a quarts sleeve allows more UV light to pass through it than the equivalent glass that why the equivalent UV rating is doubled for them. Also, you know when the UV bulb goes out because the transformer makes a beeping noise and the light on it turns from green to red

[@ReefDorkXtra]

Interesting, thanks.

[@Merknilash]

These don’t seem to be available through Deltec USA yet I’m curious how they compare to aqua ultraviolet - because a 57 watt is about $500 from them

[@raffoharper8588]

Can you put a link to the 48w uv? Thanks

[@ReefDorkXtra]

Done - links now in the description

[@barryjones6134]

Deltec bulbs are made of quartz not glass so more UV is produced compared to a normal glass UV bulb

[@bambufan]

I have the 39 W model. The gasket sucks. At some point the water will leak and go through to the electric connection, and as a result you will have a short circuit, a power outage at home and a fried power supply. And the replacement is about 90 €. After my second catastrophic failure, I put some teflon band around the gasket.. I hope it will work. But I believe the design is wrong. You cannot separate the electrical connector from the saltwater with a rubber gasket which will degrade.

[@mikeym7609]

Mate a 10 watt UV steriliser is not going to do that much to parasites,. I get it that is a nice compact size UV but the longer the sleeve of a UV the more contact time it has to damage parasites. If you wan't a compact one you better get the Aqua Medic ones. Water goes through the Aqua Medic ones in a swirl around the UV bulb for better contact time. For killing or damages parasites water should also go slowly through the UV unit.

[@vascojardim6703]

I’m sorry mate but that UV is not nearly enough to achieve proper sterilization in your tank. At its max recommended flow rate of 500L per hour (required to achieve sterilization at 33,000 microwatts/sec/sq.cm) you will be well below 1x tank turnover, which means you will not efficiently process the amount pf water required to achieve your goal. For that you would need to have the Deltec 39w unit.

[@vascojardim6703]

Just saw you also got the 48w, although did not know that existed. I had the 80w in my 200G for about 5y until it disintegrated

[@vascojardim6703]

However… according to some sources the amount of radiation required for Marine Ich is about 180.000 microW/sec/sq.cm, which would mean you would need something considerable bigger… That is why I had the 80w, which according to Deltec has 2x the radiation of normal UVs (because the bulbs themselves are made of quartz instead of glass) which (maintaining the same flow rate) would give me about 66.000. Still not there, but we need to keep it realistic.
