please help, (my fish are dieing)

[electropleb]

ok, I need help plz.

over the past 2 weeks now, my fish have all been hiding in the rocks. :ph34r: I've had my water tested and it came back perfected, apart from the salt was a little high. I took out around 10g and added around 15g of fresh water, (not from tap) :blushing:

but my fish are still hiding! looks like I've got a lot of brown algae with a lot of air bubbles. my 2 tangs look like they have ick. but I've been told the fish wouldn't be hiding! :confused:

also my fish seem to only die at night, its like the 2 nights that have gone, 2 fish have died each night. :mad:

dose anyone know whats going on,

are my fish not getting enough air, is all the brown stuff taking it? (the brown stuff (like a brown out) has bubbles in it!

help help.

a little more info on the setup would be helpful like:
size, age, occupants, when they were added, flow, filtration etc. Do you know what the test results were? Howd they test?

Looks like the sailfin could have ich but also looks like it has microbubbles on it? any microbubbles in the tank?

The brown algae comes from silicates in your tap water and sand, will go away with time to be replaced by other algaes. the bubbles are from the gases that its producing via photosynthesis so that means that it using CO2 and making O2.

This may be a long shot but do you hear loud clicking noises? I doubt it's a mantis shrimp but you never know. Could be stressing out the tangs and killing stuff at night.

I know here we go with another phosban commercial but it removes silicates and works fairly fast. So if the water tested good, Im assuming it isnt cycling. How long has it been setup? Can you describe the white on the sailfin? Ich, velvet and brook(which is more targetted for clownfish species I believe) all make a whiteish coating. I would search for marine ich or marine velvet first. Then as a long shot brooklynella. It might be worthwhile to setup a qt with copper. If you believe it is velvet I would yank them out quick. If it is ich I would yank them out as a last resort but feed the tank fairly heavy. A uv sterilizer would help to kill the parasite if that ends up being the case. Good luck.

that ought to get you started. The brown algae(diatoms) is fairly normal especially with a new tank or lower flow areas. I have a little patch in my tank as I type. It will starve itself out unless you keep introducing silicates.

ok, I've had the Tank with fish in it everything good, over a year.
its a 125G tank, I have a sump (Te one with blue balls) for a 300g tank. (just in case I got a bigger tank)
I have a protein skimmer, Coralife Turbo-Twist UV Sterilizer, (but the bulb just went out) so I'm guessing I have a good set up. :angel:

its not a reef tank, just have live rock and fish in it. I always go to awannapets, and ask them to test my water, and the test results were good. spot on. salt was just alittle high. so I took out around 10g and added 15g. I have a glass salt tester like this one (see pic)

FWIW, I tested my floating hydrometers (3) against a refractometer... all three were between 4 and 10 points off!!

Another long shot but are you running heaters and if so are you turning them off at night with your lights?

I am going to pull one from the past, have you checked for stray voltage?

[electropleb]

how do I check for stray voltage? I cant feel anything!

I did turn my heater off and at night only my 4 blue LED moon lights are on

[txav8r]

AC Volt meter. black lead to ground or the screw in the coverplate of the outlet (paint removed) red lead in the water.

[electropleb]

ok, I have a techmaster volt meter and I had nothing. (I dont know if I tested it right) I just put the red and black pins in the tank 3 inchs apart.

I'll try again! your way opps.

[electropleb]

ok when i do it the proper way I have ac 2.00 v when everything is off and unplugged and 4.53 v when the pump is on, and 16v when everything is on


thats if I'm doing this right?

I live over near Marbach and 1604 if someone wants to come round and show me, take a look

[allan]

16 vac seems quite excessive.

whats a normal voltage? is their is a normal! with just the pump I have AC 7.8v when i have the 2 pumps (1 for skimmer) and the air on I have AC 14.9V

both my pumps are in water! would it make a big difference if i took them out the water? or is that a dumb question!

[electropleb]

ok peeps, I've taken the pump out of the water and now its AC 5.8v :applause::applause:

[txav8r]

Get a grounding probe. That should take care of the problem. Be sure to get one that is made for a saltwater aquarium.

[alton]

Jack is correct. And remember Grounding Probes are only to be used for stray voltage not stray current. Stray current is when you get shocked. Stray voltage has been blamed for lateral line, fish not eating, and many other items.

[electropleb]

ok, just got home, and now its up to AC 8 Volts, whats going on?

dose anyone know where I can get a grounding probe here in San Antonio?
