They would not know anything about Tums, Col. It is a petstore, not a pharmacy. Tums is calcium carbonate tablet meant for heartburn and calcium deficiencies.bigcol;3508537; said:Im beginning to get the impression i dont just have to do the water hardness once Lupin, im guessing this will be an ongoing thing?? correct me if im wrong, if so i will ask my lfs about tums also for future reference and/or use. I dont mind a bit cloudiness of the water aslong as the fish are happy they could live in black water for me if it helps them live hapily ever after. Anyway im off to get this substrate out the tank now and do a 25%-30% water change when its all out, im sure it will stir stuff up in the water once i move it all, even though it does seem to be spotless gravel. bbs with a test, maybe sometime tonight.
The hardness issue is an ongoing issue. The hardness levels change when you change your water with a different hardness level.
