It does not leech ammonia. I've been using it for about 4 months now. I do really like the look but as someone mentioned earlier its hard to use with plants since its so light. I'm trying to grow some emeresed HC in it right now and I'm hoping once the hc roots itself it will be fine.
I was thinking of using eco complete on the bottom and topping off with this stuff so that it would be better to plant? What do you think?
It might keep the plants down better. I don't know. It really doesn't like to let plants root. I have no stem plants in mine now.
I think it might work to just weight the stems down if you wanted to go that way. Or maybe a layer of eco complete would help. Hard to say.
I thought there was someone on here who did use this stuff as just the top layer.... I can't remember who though.
Does anyone know how long it will buffer the ph? Thanks.
It really depends on the parameter of the water you use for WCs (i.e. how hard your active substrate has to work). Most of the active substrate are good for 1 to 2 years, here is a link that gives you some information.
I read from this site that some (successful) breeders don't change the substrate at all years (5+) and their shrimps are just as pretty as pretty can get. Also, I read from this site that some ppl rescape or otherwise disturb the substrate and get dead shrimp. I haven't kept shrimps for too long but my plan is to not change for as long as possible.
