the phos media has been removed and replaced with carbon, i have 2 fans that do come on with my Halides.
Just got a battery for my Fluke and im sitting at 65 volts of stray voltage with ground probe removed form the system, much higher then i had expected. I have a few things that are putting out voltage, heater 5vdc, first koralia4 8vac, second koralia4 5vac. With all pumps, heater, unplugged i still have 40vac somewhere, so i need to keep looking.
And to go back in time some i have had trouble with some LPS and others do fine with limited growth. I always thought i was just doing something wrong but the problems may be related.
Edit: i do have small amounts of nuisance algae growing on some frags. this algae was hitchhikers and has not really spread tho i do try to keep it trimmed back.
