I can't do that with Seachem Flourite.
Any of the clay based products will do this.
They contain ferts, the inert hard products do not. They might have the chemicals in them, say like SiO2, or glass, it has O2, but try breathing glass sometime and see how much O2 you get out of it.
If the Mr Aqua product holds up the SAME as ADA, it's still better in my view.
They also state something I've verified with ADA and pretty much any clay based sediment, the ferts will run up for the most part after 12-18 months.
It takes balls to put the truth up there. Won me over on that marketing scheme (the truth). If it lacks the NH4, then you can heat the product a bit more to make the grains remain intact longer.
ADA turns to mush, we have hundreds of folks that have attested to this, myself included, some batches? I've gotten much longer, it depends on how you treat the replanting routines etc.
I just know after redoing a few tanks with this, vs the experiences I've had with the ADA AS at home and elsewhere, this stuff is much better over time.
Will some folks get dogged? Maybe, but if you do several tanks with both products, now you have some statistics to back up what you say, if you only have 1 experience, well.......you really have little else to compare to, maybe you got a bad batch etc. Some folks wail on the soft sediments like these, so Black flourite sand is likely a better option.
