Instant Ocean Salt
Lee,
Hmmm...sounds fine. I have found that if the water becomes snowy when I mix saltwater, I have added too much salt and the calcium levels are oversaturated (i.e. they precipitate out). So, I...

Hi,
The 18" to 24" thing...I think that is true for electromagnetic ballast. Since the operating voltage and current for those lamps are approximately the same (within 15%), the 18" will be...

Hi,
Sounds fine...I would check if the lime desolves in water (i.e. check if this stuff is like kalk) by checking the pH when it is in water.

Hi,
Short answer...they are not design to drive the Iwasaki's properly or a standard MH (M58). They are design to drive a special MH called M138. You can try, maybe you can try an old bulb...
