I am redoing the plumbing on my tank, I am wondering after glueing the PVC doI need to do anything special? Will the live stock be ok with the glue? How long should I want until I start running water through the PVC again? Thanks for the help!

Question? When ph probes start losing their calibration, which way do they shift the readings to? Do they read higher or lower? Maybe they are all different?

I wanted to get people's thoughts on using chemi-clean to get rid of red slime. I have used it in the past but it seems very hard on SPS coral. The slime is not all that bad (YET) but it is getting on my nerves!!! Let me know what you guys think!
