CRS loosing white and dying, temperature?

[anh]

ph roughtly 7.2 goes down to like 6.9 with c02

GH 6
kh 0 or very low

been keeping them in the same ater for 3 months i had over 10 of them all had nice solid color during the spring when temp was around a stable 70-74 degrees. Now temperature goes up to 78 and i have to cool it down my best with ice water bottles to 74 but it rise back to 78 after about 4-5 hours. I cut down my lighting by half to help too.

First sign was inactivity, second sign was losing color, third sign well i lost them all except two, and they are looking like they are losing color also. I had this tank for a long time so im guessing its already cylce properly.

So did anyone notice or lose any shrimp because of prolong ex-poser to high temperature, especially with the sign of losing color etc.. This probably have been happening to me for at lease a month but i didnt notice it till now, i also lost a corydoras but i suspect it was sick beforehand (pale white color)

Your ph is too high and also you need it to stay stable with CRS.
Use a buffer soil like ADA Aqua Soil.
Also don't use CO2 with CRS.
High temps/fluctuating temps is not good either.

I've read that you can cool the temp down by adding a fan at the surface.

2 thing you can do.

First like Jimmy said. Get a cheap personal fan (Target/Walmart). There are like ~$8 each. Hang them above the tank and blow across the surface of water.

Second, add air bubbler. Airrate the water help.

My room temp. is mid 80-90 in the summer. My tank is around 77 or lower doing this. Just more fan on bigger tank

Ya I would say your the same.
PH to high, unstable condition will kill them. Co2 is a nono to regulate your ph (if thats what you were trying?)
And yes Jimko said, just grab a fan and aim it at the surface. I use fans on all my tanks and it cool my tanks down from like 82 to 74-76.

a high pH won't kill CRS. They won't breed but it won't kill them. I throw my culls, drop and plop, from a 5.5pH tank to a 7.8-8pH tank and they live in there, so don't blame pH for deaths.

[somewhatshocked]

Yeah, likely not pH-related at all.

Could be the temperature swings but that's also not a definite.

If you're running CO2, that leads me to believe you're dosing fertilizers. Are you doing so? That could present problems for Crystals, though not definitively. I've kept them in EI-dosed tanks in the past with no problems.

Could you tell us more about your tank? Perhaps provide photos, as well?

[GeToChKn]

Oh, and my community tank gets up to 82F or so with the CRS culls in it.

With the info you've given us, I suspect the temp. Or maybe something on the water bottles. The cory isn't related IMO. But I'd like to know why you're using CO2 and if you're using ferts.

This is what I use to cool down my tank. http://sites.target.com/site/en/spot...ywords=Vornado. $20 at Target. It sits on top of my light, points down into the tank and even though only half the air is reaching the water, it cooled the tank from 77 to 70 in about 6 hours. With a heater, I can keep the temp totally stable at whatever temp I want.

i have a huge house fan that i blow directly into the surface of the water, even then it only brings it down to 77 f. I dont think its my PH, when crystal die form high ph they dont lose their color and look lethargic because they usually die during molting.

I am dosing fert, 0-0-3 iron and magnesium from kent. THe only thing i can think of is the temperature swing from 74 degrees at night to 80 degrees in the day time.

Why were you using CO2?

And trust me, using the smaller fan like I have pointed directly at the water will cool the water. So try to find a smaller fan.

i always been using c02, i had them for more than 3 months with c02, they where born in my tank and grew up there too. my tank is 46 G Bowfront so im not sure if a small fan will be as effective as the big fan i have now.

Do you have a heater?

Try a 6" clip-on fan on the side of the tank. I tried that on my 13g and it dropped the temp 5 degrees in less than an hour.
