Snails and Low pH

Someone recently told me that keeping snails at pH less than 7.0 is bad since their shells will deteriorate, and that ph7-8 is best. This is a bit of a problem since my pH has to run 6.7-7.0 in order to keep CO2 up at a decent level for the plants (30 ppm). Anyone have any first hand experience intentionally(!) keeping snails at slightly less than neutral pH?

Maybe I'm crazy , but I recently got some red ramshorn snails and a blue trapdoor snail and find them to be quite fascinating. Some nerites are on order too. The hope is that I can keep everything from getting out of control. Maybe the pH thing is bad news though?

ph of less than neutral will start to erode(sp) their shells. The acidity in the water is the cause of this. You also need to have a decent kh, my guess would be 6+. You could add kh to your tank by adding crushed coral to your filter. This will rise your kh and your ph and will make it harder for CO2 to dissolve, but your CO2 should still be fine. I currently have red ramshorns, mystery snails, and a few smal spixi's. I havnt noticed any erosian on their shells though I have had them for about 2 weeks. My ph is in the 6.8 range and my kh is 7. I do not belive that they will be dying from my ph and I judge that they are more than happy with my kh. I also wouldnt reccomend adding kh to your tank if you currently have soft water fish and/or plants. I hope this may clear a little up. I am no pro on this so if anyone else wants to correct me or add please do so, you will be helping me learn as well.



I raise my sword in the air in the battle against clado. I have been beaten in this battle but the war is not over. As my wounds heal I amass another army, an army with many legs, an army of Amano's......

I thrust my tridant into the mass of medusa like staghorn. I am wounded but I refuse to take a knee.

I have nerites snails in a CO2 tank and their shells do erode. Seems do be worse on the snails whose shells were already scratched up. I started with 35 nerites and I have at least one die every couple weeks. not sure how to keep them alive in freshwater for a long time. I've tried adding reef calcium but maybe I should up my PH and KH some more. My CO2 recently ran out and I am using Excel right now but the nerites keep dying off. I have some with nice complete smooth shells and some with barely any shell left at all so I am confused.

Is it cruel to have all my 200 pond snails in 6.0PH water?
