Hahaha, no parades rained on here mate. This is simply an experiment going in the opposite direction to carbon dosing.Sorry @slin1977 ,
I don't want to rain on your parade, however in that pictured tank there is only one fish and the sand bed looks very clean so I assume your doing regular WC aslo .
these two factors wouldn't cause the tank to have a huge load to combat.
Sorry for the confusion , that was a photo taken 2.5 months ago when I first threw in the media.
I documented things better on my TJ and will bring over some photos to this thread.
What I can show you is a photo taken when I was away from my neighbor , no glass clean in 2.5 months, no water change in 4 months. Yes there are two fish in the tank, bear in mind that most of the food ends up in the coast to coast and most fish tank sitters are heavy handed when it comes to feeding too.
Anyway what's more interesting is now that the Siporax is nearing maturity, tested tank water was 0.00 for nitrate and phos - three slabs of fresh flat rock were thrown into the display. Look forward to seeing how the Siporax copes with that as in the past I've had up to 0.50 phosphate leach out into a bucket in 24 hours.
