DINOS....again....What to do?

[redspot321]

Hi After a 6 month battle with the mighty dinos they have returned.
The first time I rid the dinos by bringing my TDS to Zero. Well my TDS is still zero but the dinos seem to return when I replace the sandbed I removed months ago while the battle was going on.

I have tried this three times over the past two months. I actually boil the aragonite before placing it back in the tank every time for 10 minuted.

I love my sandbed, what could be causing the dinos to bloom when the sand bed is added?

What's your pH? Try raising it to 8.4 or 8.5 or even 8.6 for a day or so. Dino hates high pH.

Someone in the Chemistry Forum had a formula for spiking the tank with a kalk mixture, but I'm not really sure what that entails
and what you have in your tank.

I had Dino and raised my pH, got my TDS down to 0 and they're gone... for now anyway. I'm also running Rowaphos, GAC and de=nitrate. Anything that will help.

I've had really good luck with polyfilters and phosban.
