Hammer not opening anymore.

My frogspawns are also acting in the same manner. This has been going on few a couple/few weeks now. The numbers below were posted yesterday before a 20 gallon water change in my 60 gallon cube (excluding sump size). I will redo the next tests within a couple of days. Before, these 3 heads would open up so much you though it was all just one big softball size head. Now, the photo below.

Over the last several months I've been using Vibrant to rid a tank full of bubble algae. Since this is a recent occurrence, I don't believe it has to do with Vibrant, just thought I would mention it.

Might be worth trying to run some Purit and seeing if that helps them by removing whatever it is that's upsetting them atm.
How long have you had them for?

I've had them around 6 months. I've also lost a candy cane that was knocked over in the sand and left there for a bit. That is all black and I'm about ready to remove it from the rock. I'm not sure of those dying would cause a chain reaction or not though.

I wouldn't have thought so. A bit of a stab in the dark really, but definitely worth a Purit try.

Have you used it before, or have any?

 

[JPR]

Nope. Only other thing I've tried in the past is a 2 part from Brightwell.

check it out, I keep a small tub in my cupboard just incase, as sometimes you have these unexplained issues and when you test the water things appear fine, but we can't test for everything.
