Thanks....this is my first try at official reef rock. It is very brittle now but I assume it will harden up considerably as it cures in the next couple weeks?
Also, on the subject of Perlite..... I did a TDS test on the stuff today. My tap water has 147ppm as is.....after my RO/DI unit I am at zero. I filled three plastic cups (one with tap, 2 with RODI and tested TDS on all three to make sure I get the same #'s. One RODI cup was used to rinse off particles from the perlite so I could test the chunks after they soak in the other RODI cup for 1/2 hour. I am surprised at the initial results.........Both the RODI rinse/prewash and the "official" soak cup still register ZERO TDS after 1/2 hour with the perlite. I will leave them overnight and test again tomorrow.
