I have Gone To The beaches In south carolina For A few Years Now And I have picked Up Some Shells While I was done their A few Times. Is It Ok To Add these Shells To raise the Ph Of The Tank For My Brichardi Or Not?


Thanks
 
Yes. Just be sure to clean them well.
 
The easiest way is too used crushed coral sand (or gravel) as a substrate. Or you could use liberal amounts of limestone or other alkaline promoting rock material for decoration. You could even use dead coral rock, like a saltwater tank. Putting a couple of seashells in there is not really going to do much, unless you have a really small tank.
 
I was assuming that you were talking about many shells. Also what is the pH of your tank right now? Crushed coral or shells won't make any difference unless your pH is 8.2 or less. The shells won't dissolve in a 8.2 or higher.
 
Ooo Ooo! A guy at Big Al's told me the easiest way to raise ph and water hardness is to add baking soda to the water. About 1/2 teaspoon per 10 gallons i think he said. I have a malawi cichlid tank, and i added a teaspoon and a half for my 33 gallons. The ph went straight to 8.0 and the water hardness went up, however it is not where i want it yet, but pretty close.

I have crushed coral in my gravel and it only raised the ph of the water up to 7.4, then it stopped. It probebly takes quite a while to work. Baking soda is easy and fast.

That's what he had been using for his malawi tanks, and since i am buying my fish from him, i figured it was ok. I don't know if the baking soda would affect a fish that hadn't been kept in it before though. Not really sure.
 
Baking soda will work, but it tends to be harder to control pH (and KH) stably than if you use something that gradually dissolves. Aragonite sand works nicely, either as a substrate or in a filter bag, tucked away in a filter somewhere.

Yeah I've done it before. I have crushed coral in a bag you get from the pet store in my filter to help raise my PH. It does pretty good.
 
Hello,

I agree, I have a crushed coral Cichlid substrate in my tank along with a healthy dose of limestone rock and my Ph stays at about 8.0 consistently. Good luck, I hope this helps.
