Need some feedback on possible causes and solutions to my 75g tank.
The tank is already established. Before this the tank had really
clear water. Filter is clean as well or as clean as I guess a
canister filter can get.

Anyway, the tank is heavily planted with compressed CO2, and 7cc of
TMG dosed daily and ~210w of cf. Anyway, just the past week the water
has had this milky color to it. The plants are still doing great with
no adverse affects that I can tell and the regular 50% weekly water
changes is only clearing it up temporarily. About 24-26 hrs after the
water change, its back to being milky. No adverse affects on the fish
that is noticeable.

Anyone have any ideas of the cause and a really low cost solution.

thanks

typically this is a sign of bacteria. vacuum if possible and don't feed for
a day or so.

ease off on the amount of food.

Overfeeding has been ruled out. I feed about 3 times a week and the
fish get just enough to keep them from snacking on one another (there
all small fish anyway). A few pellets hit the bottom for the corys
but other than that, thats all. Will be doing regular water changes
for awhile until I can get it back to its original view. Thought
about putting a carbon filter in to help clear it out but am unsure if
this would help in the long run or not. Anyone else have an idea of
what could be causing this?

thanks

It might help if you post your parameters. pH, KH, nitrate, etc.

Is it possible that your cloudy water is actually the beginnings of green
water? Often, a slight green water problem looks whitish or milky. It's not
until the algae gets really bad that it starts to look green.

Make sure your CO2 injection is working properly. I had a very similar
experience with my 70 gal 240 watt tank. Water crystal clear, plants
pearling all the time... and then over a 2 day period BAM! cloudy. Water
changes had no effect. I couln't see through to the back of the tank-it was
so cloudy. So.... I checked everything and my CO2 reactor was
malfunctioning. Cleared the problem and two days later the water began to
clear. In 5 days the tank was crystal clear again... worth a try!

Throw a diatom filter on it. In half an hour it
will be crystal clear. Don't be surprised if the
filter turns green.

Hi,

as one of the other posting sais, I think it's bacteria'bloom'; cloudiness
in this case should look a bit 'silvery'. It should disappear/decrease
within about 24-48hrs. Best thing to do is to let it rest, but keep an eye
on O2/CO2!
If this is not the case, better check your whole chemical scenario and post
it again.

Jos.

The tank is still cloudy. Here are the specs

pH 7.2
kh 20 dkh
gh 16 dh
p 0
ammonia 0
nitrites ~.15 if that

Haven't had a chance to check the CO2 reactor as mentioned earlier.
Will give this a shot. Its looking as if its an algae bloom.
Overfeeding is not an issue. Not a lot of mulm in available areas.
Fertilize ~8 cc daily, 210w cf, ~11.5 hrs of light daily, 20-50% water
changes weekly. Am still baffled at the cause. Have some string
algae growing and the SAE dont touch it (worthless things) and there
true SAE. Anyway, what's everyones thoughts on this. Plants are
doing just fine. Have thought about reducing fertilizer amount and
light lvls or one of the two.

check your nitrAtes. that's where my algae bloom comes from. Adding
plants will get rid of it.

This might be the problem. Nitrite should be zero. If nitrite is measurable,
your tank is cycling. Cloudy water is to be expected.

Nitrates will usually not cause an algae bloom. What several people
have found is that if the ammonia being produced isn't being used up
quickly enough (by either the bacteria or the plants) then it will
cause algae problems. The ammonia might not be measurable, but it's
still the most likely cause.

My 75g tank was running for 4-6 months with nitrate level of 50ppm+
with zero algae problems.

Not clear on that, Chuck... ammonium nitrite nitrate, right? Assuming a
fully cycled tank, whatever ammonia isn't being used, ends up as nitrite,
then nitrate. Or am I putzing up the chemistry thing again?

The presence of nitrates is symptomatic of an algae bloom but not the cause
of it. If there is more ammonium present than the plants can use, the
excess will be available to be converted by the bacteria to nitrite
nitrate. Algae are opportunistic and will use the ammoium or nitrate
indiscriminately whereas higher plants will exhaust available ammonium
before using nitrate.

So yes, the ammonia will eventually be converted to nitrate.

In my experience, nitrate level itself is un-related to an algae
bloom.

In my tank, the rate of nitrogen production is higher than the plants
can use, so the nitrate level in my tank constantly rises. But,
because of the massive biological filtration capacity of a wet/dry
filter, the ammonia is converted QUICKLY into nitrite/nitrate.

In my 10g quarentine tank, with no fish in it, if I add lots of KNO3,
to get a nitrate level of 50ppm, I get no algae bloom except for an
increase in green-spot algae on the glass. I've held the nitrate
level steady at 50+ for over a week testing this. If do a 100% water
change, and then add enough ammonia to reach 10ppm ammonia, I'll have
algae soup in just a day or two.

Algae seems to be able to utilize ammonia MUCH more efficiently than
it does nitrate.

Kind of odd for it to start cycling again as it was already cycled
before the bloom. I did do a no, no. I cleaned the filter when I did
a water change but this was after the initial bloom started so this
probably didn't help any. Will do regular water changes every couple
days in hopes that this will help clear it up and leave the filter
alone. Thought about doing something like a 95% water change,
otherwise, suck all the water out down to the gravel and refill but
this may be a bit drastic. The fish may suffer a bit but but there
all hardy fish anyway and they've been through worse. Will try to get
the nitrites to 0, clean the CO2 reactor. Unfortunatley, funds are
tight, so a UV sterilizer or a diatom filter are out of the question.

Did anything happen that might have affected the biological filter? Dead fish
or snails, medication added to the tank, food you don't usually use, plants
pruned severely, power outage, new fertilizer, etc.?

It might be best to just let the tank alone. Let the biological filter
re-establish itself, and the problem may go away on its own.
