Hi,
Does anyone know the pros and cons of using concrete in an aquarium? I have a 100 gallon, fresh water tank with a couple of large decorative objects inside made of concrete -- a Buddha head, and an Angel.
My water always tests very high alkalinity. I keep trying to lower it with PH adjusters, and it won't budge. I'm beginning to wonder if it's from the concrete objects? Also, it seems a lot of my fish die for no apparent reason, because the water otherwise tests fine.
Thanks
