Hey Andy
I dont know if i buy into the dangers of ozone in the household. Once ozone contacts anything it immediately oxidizes and releases balanced oxygen molecules. The only way it would cause problems is if you were leaking too much into your house over a continual amount of time. We do not exhaust our facility, and i think i am okay(well maybe not) The very miniscule amount a hobbyist would run seems pretty insignificant.Either way, if you do breath too much, you will notice a sharp shooting headache, and a very distinct smell. Have you ever seen those central air home purifiers that people hook up in their duct work? They are using ozone to knock down bacteria,mold,etc. I think they run some sort of a carbon filter in the loop but, you would do the same thing in a aquarium.
Donnie & Kim,
I am not sure, is nitrogen cycling a problem with your system? If i had to answer now, i would say no. Denitrators are more problematic then they are worth, and if people spent as much time cleaning and/or setting their tank up correctly in the first place, they wouldnt need to be farting around with a denitrator! I have had two customers of mine crash their whole systems with these wonderful devices, and both of them asked me if i thougt it was a good idea, and both of them did it anyway. The funny thing is that both of them were rubbing my nose in it evertime i spoke with them. They bragged about how low their nitrate was,but it didnt matter to me, i run my systems in a more natural, holistic approach and have 0-5 nitrate. After a few months, both of them suffered huge, catastrophic failure of their systems. The reason why, they got behind on maintaining the filter which is a very bad thing, and alot of corals and fish died because of it. I think these denitrators have become more practical and can yeild great results if you stay on top of it. I just dont see the reason to have one in the first place. I always say"if it aint broke, dont fix it" and this holds true with reef aquaria. Why hook one of these things up when you can get the exact same results in a more user friendly manner?
I could only see the benefit in certain types of applications, but not for a standard 200gallon reeftank.
If you need any advice on anything, you can ask me here anytime, or pm me and i will give you my phone number and we can talk about it.
