Substrate heating
sorry I didn't elaborate, but what I've read is that the current created by
the substrate heaters in concurrance with turbulence created by HOT filters negate any postive affect a SH can offer... is that better? I dont' have any reference for this, just what I've read over the last 2.5 years or so.... "Christopher" wrote in message rthlink.net... is this the rational behind buying a substrate heater? "BuddyGardner" wrote in message ... dont' waste your money.... Can using substrate heating eliminate Anaerobic activity in a compacted substrate, through means of convection? |

Are you saying that a HOT filter defeats having a substrate heater, or that a HOT filter does the same thing a substrate heater is suposed to?

What I read, was saying that the uplifting currents created by a substrate heater, has to battle the downstream current put off by a HOT filter... heat rises, HOT flows down.... the uplifting current is only affective for the lower 1/3 to 1/4 of the tank, which means, what is pulled out of the gravel, is put back in the gravel somewhere else... |

Substrate heating
I only knew of 1 person that had one.. for about a year, until it went out,
then they lost the whole tank due to a huge temp swing... you can't see that it's not working... you have to feel the tank... atleast on hers it didn't have an indicator or light that said, I'm working....

? I wouldn't think there would be enough temp difference to cause
stratification from either. 8' deep ponds in the summer don't even strat. wrote in message ... sorry I didn't elaborate, but what I've read is that the current created by the substrate heaters in concurrance with turbulence created by HOT filters negate any postive affect a SH can offer... is that better?
