PH Crashed Damn what's going on Now!
 

PH crashed in my 33gal three days ago.
stats were ammo 0, Nitrite 0, nitrate 10
but PH crashed to 6.0, KH was 0, kaput, nonexistant.
GH was very very low like 10. My Pleco died.

Did 50% water, PH only went up to 6.5, KH was still really bad.
Waited 12 hours and added 1 teaspoon baking soda.
PH went back up to 7.5 KH was 60 and GH 80. Fish got much
happier.

Today fish are acting all funny like they are hurting again.
Some are sitting on the bottom, most are bunched
together and hanging out near the filter inlet. Two of them
have minute signs of fin rot or look a bit frayed on the tips
that seems new. I rechecked stats all seems normal.
PH 7.5 KH 50, GH 60, ammo 0, nitrite0 nitrate10.
Did another 30% water tonight and they seem much happier
again.

Tank is a bit overstocked but it's been running a long time
and never had these problems. I'm running a good airstone,
an Aquaclear300 with lavarock and biomax media, temp is
72, i use 48hour airstone aged temp matched water with
recomended shot of dechlor. I also run a 0.05% salt solution.

I usually do a 30% water
with gravel siphon once a week. However, now i really
really siphon the gravel, I run a garden hose to the basement
so it really gets the krud out. My Nitrates are really low now,
always less than 10ppm. Could it be i'm overcleaning the gravel
and killing off good bacteria? If so shouldn't I see ammo or Nitrite
spike? Did the PH swing cause long term damage that will take a
while to recover? Did the PH swing hurt my biofilter? If so wouldn't
I see a spike?

Anyone have any idea what's going on here?

not sure why your PH crashed in the first place, but your fish "might"
not be happy because you raised the PH too fast

PH Crashed Damn what's going on Now!
 

Ive missed the beginning of this thread so I don't have the full picture but
why on earth are you missioning so badly with the ph???
STOP IT.....leave it alone. Your fish will be fine!!! Try and keep it stable
rather than adding all sorts of crap that keeps shifting it all over the
place. Thats why your fish are dying!!!!! Just say NO :)

when there is an inobvious problem with fish acting toxed out, or worse, fish dying
move the fish to a bucket of fresh water and then clean the tank out. your gravel
sounds like it has gone toxic. Jo Ann had every test known and she would get a
situation going where the fish were acting weird and NOTHING showed up on the tests
and she would just move the fish out to a new tank and she would empty and clean the
old one. some things cant be "figured out" in time to save the fish.
the longer any tank has been set up the more likely the tank has gone toxic somehow.
what kind of gravel you got?

What is "fine" about my Pleco dying?
I guess you missed that although it was in THIS post.
You also missed that i raised the PH slowly
over a 24 hour period, first 12 hours with a 50%
water, and another 12 hours with the soda.
I guess you also missed that the soda made the fish
much happier. If I took your advice, and that would be do
nothing when your PH crashes, my fish would probably
all be dead by now and i would be a happy camper NOT!...

Thanks ingrid, i like where your going with this.
I have standard rainbow coulored Aquarium gravel,
bought it 5 years ago and been using it ever since
with no issues.

What I noticed that is weird is, i'll approach the tank
around feeding time, fish seem allright, they hang out at the
surface, i turn the lights on and feed them, they eat a bit,
then they dart around like mad and stop eating alltogether.
Could it be the black crud that accumulates on my aquarium
lid (i'm using egg crate material like the stuff to diffuse lights)
leaching back into the tank surface water? Is that stuff toxic?
Am I overcleaning the gravel? Is 10ppm Nitrates actually a
good thing?

I know the food is good cause I use it in my other tanks, no issues
with the other fish.

Still I suspect my water hardness is too low. My KH out of the tap
is around 30ppm or less, and when this whole thing started the PH crashed
and KH was 0, could toxins cause something like that?

PH Crashed Damn what's going on Now!
 

unfortunately, the source you give is confused.
first of all, it doesnt take a lot of hydrogen ions to have the pH drop. In
distilled water there is no "buffer" so just a slight excess of H+ ions sends pH
spiraling downward. When there is a buffer present, the excess H+ hydrogen is
neutralized. The purpose of a buffer is to "resist" changes in the pH.
And rise in pH is due to an excess of OH- or hydroxide ions. Again, in distilled
water it doesnt take much OH to make the pH climb. And the buffer resist the change
in pH by neutralizing the excess OH-.
http://members.aol.com/BearFlag45/Bi...eviews/ph.html

The major source of CO2 in water is from the air. Rotting vegetation will put CO2
into the water because it is one end product of bacterial action. A plant that is
submerged will use up CO2 during the day and put out oxygen. At night it uses up
oxygen and puts out some CO2, but much less than it is using unless the plant is dead
and decaying. Plants that only have their roots in the water will not even put that
much CO2 into the water. CO2 cannot dissolve endlessly in water. At around pH 6.4 no
more net CO2 will dissolve in water it just goes in as a gas to a limited extent.
that is, it enters a steady state with CO2 going into solution and coming out of
solution at the same rate. Fish can do fine at pH 6.4.

What pushes the pH down below around pH 6.4 is the presence of organic acids. Dead
plant matter and feces that are undergoing anaerobic digestion by bacteria will
result in partially digested organic breakdown products. These are acidic and can
continue to build up as long as there are bacteria that can live at those acid
conditions. When there is an abundance of oxygen where bacteria are "working" they
will break organic matter down to CO2 and H2O plus other non-toxic compound.

Organic dolomitic limestone is a good source of buffer having both calcium and
magnesium. Oyster shells have almost no magnesium
http://www.eggcartons.com/item653.htm which is one reason they are used as grit for
chickens --- magnesium evidently inhibits egg laying. I put the ground up organic
limestone loose in my filter where it is dissolved as needed. Not everything that is
lime is safe. There are limes that are unstable and cause pH to swing up and down,
there are limes that just keep going into solution to high pH and kill fish.. like
quick lime. So always, always try a handful of the lime material in a gallon of tank
or pond water and test the pH over a couple days to make absolutely sure it is safe
to use.

When baking soda is put into acidic water CO2 is liberated. Put a LOT of baking soda
into a very acidic water and a LOT of CO2 is generated which means that until that
CO2 has time to out gas and leave the water it is very toxic to the fish. Fish are
no different than we are. We cannot have high levels of CO2 in the air even if there
is plenty of oxygen. Fish cannot have high levels of CO2 in the water even if there
is oxygen. It is important to slowly add the baking soda WITH plenty of aeration.
It is the aeration that moves the CO2 out of the water. Vigorous aeration that
breaks the surface speeds the release of excess CO2.

And the big point should be that it isnt just the increase in CO2, it is the lack of
oxygen in a system that results in the accumulation of organic acids that leads to
acidosis and death in fish. So this is why bare bottom tanks are so good. There is
no where for rotting organics to accumulate and be broken down anaerobically. Well,
unless the filter is a closed system. One reason I like my hang over the back
Whispers is the filter is open to the air.

You did right in raising the pH but with aeration you could have raised it much
faster. Changing the pH from acid to pH 7.0 will not cause big problems. They dont
undergo the same kind of shock as going from acid to alkaline, or alkaline to acid.
Baking soda is a temporary fix. You need to get the hardness up, a good buffering
system established. Ingrid

sorry, but that colored and maybe coated gravel breaks down and becomes really toxic
all on its own, even without being the site of anaerobic digestion. you are not over
cleaning your gravel, it has gone toxic. get it out, if you must use plain old pea
gravel.
yes, the black crud could be a toxic type of algae. bleach the lid, rinse well of
course. and get and use some organic dolomitic limestone. you can get this at
garden centers. it is usually quite gritty, white powder with darker gritty pieces.
try it out in a bucket of water for 2-3 days first, pHing it to make absolutely sure.
make sure it doesnt have any additives. mine actually just sits on the bottom of my
bare bottom tanks. please, dont consider using plaster of paris in any form. it
wont work. Ingrid

Gravel will raise hardness if it's the "wrong" kind. Pour some acid on the
gravel, does it fizz? Kodiak's problem was lack of alkalinity.

you
are not over
cleaning your gravel, it has gone toxic. get it out, if you must use plain
old pea
gravel.

Kodiak, common practice is NOT to clean the entire bed at one time. If you are
serious, install a UGF.

yes, the black crud could be a toxic type of algae. bleach the lid, rinse
well of
course.

She's making it up.

Good luck Kodiak, too bad she's feeding you voodoo.

Thanks for all the info Ingrid, I have a descent airstone and big
Aquaclear300
for a tank that small (33gal) but I didn't want to chance it and get too
much CO2
in there so I raised it slowly. I will definitely look into the dolomitic
limestone as
you mentioned in the other post.
