firstly
y, sorry to hear this bud. here's to a speedy recovery!
Guys, im pro using everything again, even if its as deep as the tank itself id still use the sand. technicly i agree with what you guys are saying, but pure oxidization would have the same effect regardless. & Its bactera, you would be supprissed as what can survive & for how long. bactera has been around since creation of life itself, i think billions of them can handle 3 hours of being scooped into a bucket from our sissy 5 inchs of industry standard covering.
hell - id even use 100% new water if i had to, your animals werrn't born in a bubble remember. we're getting so caught up these days with the cutting edge findings or publications that we're forgetting one very important & fundimental principle, you earn your right to survive in nature, just cause we capturing these animals in a box only means we're not dilluting in the same scale as nature - so in knowing this, factor the cost of higher water changes.
