Water still cloudy

Hi,

I posted last week about my water being cloudy. I did a 20% water change using DI water. The DI reads 0 on a conductivity meter. I've cut down on feedings making sure all the food I give my clownfish is taken before adding anymore. I tried adding a cup of activated carbon and doing another 20% water change with no effect. In fact it seems worse.

I can just barely see the back of the aquarium at this point and the odd thing is the cloudiness seems to be taking on a greenish tinge.

Could this be some kind of algae bloom in susoension in the water?

Until this started last week, my water has always been very clear.

Robert

No I didn't rinse it. Aside from removing the dust, what else is rinsing supposed to do for you?

Although the carbon didn't actually do anything, the problem only got worse two days later. And when I restarted my Eheim filter after adding the carbon, no dust came out.

I'll tale a picture tonight and post it from home.

Ok. I didn't rinse since the charcoal was taken out of the top part of a 100 pound bag so was basically dustless. And the extra clousiness only appeared two days later and is not greyish. It more greenish white than grey.

Post some water test results...pH,ammonia, nitrite, nitrate, phosphate and even calcium and alk if you've got them...it sounds like you have an algae bloom or even a bacteria bloom.

I've been meaning to run some tests but haven't. I spent the free time I had doing a water change, but I will tonight and post tomorow.

What's an algae bloom, what does it look like and what causes it?

Oh, and how do you get rid of it?

Robert

Algae blooms are just that...a bloom of algae..keep in mind that algaes can be huge macroalgaes or microscopic single celled algaes...a bloom of the latter microscopic algaes could cause the green cloudy water you describe. The blooms are can be caused by several things but usually it is an excess of nutrients in the water that feeds them. A bacteria bloom is much the same. The first step to clearing it up is to determine exactly what the cause is, algae, bacteria etc then try to figure out what is feeding it and remove it. In order to better diagnose the problem, post a pic of the tank and describe the setup in a little more detail...lighting, filtration, livestock etc.. HTH

I'll post some pics tonight and in the meantime here is my description of my setup.

I bought this setup second hand and it was about 3 months old. 52 gal tank with crushed coral sand base.

About 40 or 50 pounds LR but I havent's weighed it myself. Double fluorescent lighting, one blue (actinic?) the other white, both are on about 14 hours a day.

One rotating 160 GPH powerhead, one homemade recirculation setup pump that moves about 500 GPH and an eheim 2717, empty aside for the activated charcoal and about two inches of those ceramic cylinders that I'm using to weigh down the charcoal. The eheim moves about 250 GPH.

No protein skimer, yet.

Water changes are made using DI treated tap water without RO pre-treatment. The cartridge is new and the measured conductivity is 0 on my meter. Tap water in my area measures 5.

I keep the temp very close to 76, only slightly higher during warm days. My inhabitants are one false clown and one algae blenny that both seem happy and fit. The rest are one red legged hermit crab, big and getting bigger by the day, 14 blue legged hermit crabs, one large snail, I forget what kind, a rockface crab, a decorator crab and an emerald crab.

I seem to like crabs

Feeding consists of rotating feedings of frozen shrimp and flake food once a day. I haven't been overfeeding significantly except for one time just before this all started. I usually only feed as much as the clownfish will take bit by bit. She will sometimes miss one tiny brine shrimp but I can't imagine how that could foul 52 gal of water.

The only time I overfed was when I opened the flake food container over the tank last week. About a quarter of a teasoon fell in and were blown all over the place by the circulating water. I didn't figure that would be a problem with all the crabs I have. A few days later, the cloudiness appeared.

Coincidence?

Since this started I've cut down on feeding and turn the light off every other day.

Robert

Sounds like cause more than coincidence. Some flake foods have high levels of phosphates too.

You really should be testing your water levels frequently.
