Tank problems

[christyf5]

Ryan, no I don't have a grounding probe. I would expect larger more steady problems if that were the case. The STN has been rather sporadic, some days I don't see any difference then the next day white, then slow recession for 3-4 days then poof gone the next morning.

Jim,

I have no idea what a sandbed could be doing to my system but when I had a sandbed in the main tank I had all sorts of problems. Ripping it out seemed to pave the way to good times with my tank. I mean, I've looked at pretty much everything I can think of. Now I'm sort of eyeballing the 'fuge as my next target.

I suppose we shall see after I do another large water change today. Things looked a bit better after the last one but weren't spectacular.

I don't know where the nitrates would be coming from if I have more than 5-10??? I haven't added any fish since this started happening. Mind you now that I think of it, that damned crab killed a helluva lot of snails and left little bits behind in them (peeyew they were stinky!). Still I don't see how half a dozen snails could be causing such problems. I do a 15 gallon water change weekly and last week and this I've done/am doing 30 gallons.

Ozone is next on my list too.
