UV sterilizer
What's everyone's ideas/opinions on UV Sterilizers? Does this lead to a healthier tank, or is it a waste of time? I've read where it might help with some forms of algae and maybe certain stages of fish diseases, but I would like people's experiences on this topic.
Thanks, -- Craig Brye University of Phoenix Online |

... What's everyone's ideas/opinions on UV Sterilizers? Does this lead to a healthier tank, or is it a waste of time? I've read where it might help with some forms of algae and maybe certain stages of fish diseases, but I would like people's experiences on this topic. Sterilizers are very effective against floating algae (green water) and bacteria blooms. They also keep the germ count lower. (In aquaria, germ count is much higher than in nature.) UV sterilizers also reduce the likelyhood of some diseases, such as Ich. On the downside, they seem to make trace element dosing less effective because the UV breaks open the chelators, allowing Iron to change from Fe2+ to Fe3+ more quickly. You can compensate for that simply by adding trace elements more frequently. A sterilizer also acts as a heater -- a 15W sterilizer is a 15W heater. If you are struggling to keep the temperature low enough as is, the sterilizer will make the problem (slightly) worse. Finally, the dang things are a pain to clean. (Time between cleanings varies with the tank. 3 month intervals are usually recommended.) Bulb life is between 11 and 16 months, depending on whether you have a conventional or an electronic ballast. And replacement bulbs are fairly expensive (but shop around -- for a G15T8, I've seen prices vary between $15 and $70). Correct sizing and flow rate are important, otherwise the sterilizer won't be effective.

Thanks, Generally only useful for GW outbreaks, but not much besides that as far as planted tanks are concerned. Certainly would be a non eseential. If you have one, use it only once a week after the water change, large pruning for the next 24 hours after the disturbance. That saves the life of the bulb etc. As far as more trace being needed using one, I've never seen any significant nor noticable difference, with or without. Regards, Tom Barr |

Thanks, I've got one in my 110g planted tank for over 3 years, mainly to keep my 6 discus healthy. Seems to work and I have by chance 2 pairs that breed often. Since I put in the uv, I've not had any disease outbreak, not the case before I put it in. I've had this tank in operation since 1993 (2001 started using the UV because I added 6 discus) and do not see any difference in use of fertilizer and since I use PMDD even if there was the cost would not matter much.
