Something wrong with my tank, i think it might be too much CO2?
Okay, so my tank has been cycling for about 3 weeks now, and except for algea growth(wich will probably fix itself when i put some flying foxes and sakura shrimp in there.
My water parameters are fine, exactly the same as my low light tank except for KH, wich is higher and PH, but nothing to the extreme.
To test my water, if it would be decent for fish, I decided to put in some Red cherry sakura shrimp(i have several 100's in my other community tank, they breed like crazy).
When i let them get used to the water everything seemed fine, then when i put them in, they kept swimming to the surface(which i have never seen any of them do before in the other tank, or on the internet when looking up how to care for them a few years back) for about half an hour, then dropping to the bottom(probably being exhausted). A few hours later they seemed alright and where munching on my algea. 2 days later, all 5 of them where K.O., laying like dead on the bottom of my aquarium.
They didn't lose their color, like dead shrimp usually do, so i figured i might save some of them. I took out the ones i could find(some must have been in the vegitation). All 3 i took out and threw back into my community tank layed there on the bottom for about 3 minutes, then started moving around again.
My guess is there's too much CO2 in the tank and not enough O2, because since its a DIY system, i keep it running at night aswel?
I distribute the CO2 trough my filtration system, so the aquarium has a constant flow of micro bubbles flowing everywhere. I don't have any devices to test my CO2, nor do i have the money or intention to buy one. I had 4 bottles(5liters each) pumping co2 in my system.
I downgraded to 2 2l bottles and a ceramic diffuser to see if that helps.
Any input or idea what it might be?
