GFO- do i need it?

The other strange thing is when mother colony started bleaching if i cut still healthy branch in 60% that little frag survived!!!!! Like i cut Brown and Green Birdsnest. Mother bleached out, frag cut from her not.....

 

Check for stray voltage. It can easily kill corals, especially SPS. A friend of mine just had similar issues. After watching his SPS die and banging his head against a wall, he remembered what I told him about stray voltage. Sure enough, his return pump was going out. Now a week later, and everything is starting to grow back.

 

Yes, I did that too. Last week. Bought volt meter at Home Depot. Shows 0.009. That's good. I think like 5 volt is dangerous. So I'm way, way below. Nothing. Any other thoughts? Or it is just me. Ofcourse I use RODI water.Usually it shows 0.00 sometimes 0.01ppm.

 

Did you check everything that runs intermittently, like heaters, fuge light, etc.

 

No, I checked water in 10 different places. I thought that would be enough..No voltage in water that's what counts..???

 

No voltage is what counts but if your heater isn't running constantly you may have tested the water when it was not on. What are you grounding your multi-meter to? One probe should be in the water while the other is grounded.

 

Then I was doing it wrong. I had two probs in the water. dumb!!!!What is the best way to ground it? What should I touch? Sorry, I feel really stupid
now....

 

Don't feel stupid it's a common mistake. Try grounding to the round 3rd prong in a plug socket.
