Do substrates loose their integrity after awhile? I have laterite mixed with gravel that is approx. 3 years old. Should I remove the old and add new? Or just supplement what is there? Seems like eco-complete gets the nod. Would appreciate some suggestions. Tom

Tom,

Some substrates lose their punch over time. I understand that ADA substrates come with a recommendation that they should be changed periodically. Soil substrates and other substrates with a substantial organic fraction can change over time. People might replace them to get back to the original characteristics.

I don't know of any reason why a gravel/laterite substrate should need to be changed. I have had gravel substrates in place for 15 years without problems. But then, changing out the substrate and seeing the effect could be fun.

If you're happy with the tank, I wouldn't touch mess with the substrate. You're asking for a serious mess if you go digging in the soil. I'd only mess with the substrate if I was restarting my tank.

Tom, are you going to break down the tank for the aestetics of Eco-complete or for some additional reason?

Thanks for the info! I was just curious and wondered if you guys ever changed because laterite might lose its punch. I don't want to change for the aestetics of eco-complete and plus it would be a royal pain in the you know where! It just seems that alot of people like eco-complete, but I guess its whatever one prefers. I think maybe I'll supplement a little more laterite with what I have. Thanks for the replies. TOM
