Why not take a sample to your LFS and have them test your params as well. The chances of both test kits being bad are slim to none. If LFS comes back 0 ammonia sounds like background...
Ugh.... I dont know why I didn't think of that.
Though im scared if I take it to aquarium services they will charge me to do it
seriously though, that is a good idea.
process of elimination.
Why are my snails still alive? I have no way to tell if they are healthy/happy .... how do I determine this?
I'll be very disapointed if I have to tear out my BG.... but not because it looks so good, Not because of all the work and time I put into it........ because of all the mess I will have to clean out of my tank
I'm already considering ripping it out due to an LED failure, and to simply remove the UGF altogether.
I would make another background, but I would greatly simplify it, and use everything I learned from this go around, on the next generation
I think i would just use Krylon Fusion, and hopefully make it look good, without the need for epoxy.
I kinda still don't think the epoxy had anything to do with the deaths. Its marine epoxy, and if it was going to leech things into the water, why would they use it specifically to build objects that are designed specifically for use in the water?
not saying it couldnt be something else though... perhaps white glue? although listed non-toxic..... maybe acrylic craft paint? something in the grout possibly? thats a likely one.....
there are so many things that could have gone wrong.
another thing to consider as well, why did the fish seem to be doing just fine, and rather content up until about day 3 of no water change? at which point I noticed a single fish behaving oddly (listless, loss of swim control etc) and it was downhill from there.
And sadly, an extensive test kit for water, one that will test just about anything, costs $160.... and i think it only covers one or two tests.
