Crushed coral in filter


Recommended Posts

Hi. This is an "it depends" answer. If the water you use is really acidic naturally it will be eating away at the coral much more often (this is the chemical reaction that lowers your acidity and raises kh/ph). I put some coral in the substrate of my original tank and it's been in there over a year with stable kh/ph readings. When you put it in a filter it may wear down faster. So I would say personally the rule of thumb would be when you start to see fluctuations or if you do a complete cleaning of your filter you could replace it- but it certainly does NOT need to be replaced often.
