Time to start reading.
the main thing is the fresh water bath. once the rocks harden keep them completely covered with water and add a powerhead for movement. change out the water every 2 or 3 days for atleast 8 weeks before you even bother to start testing the ph. any earlier and your just wasting a test kit. also make sure your using a ph test kit for FRESH WATER.
once the rock is at 8.3 or below dump the fresh water and put them in a salt water bath for a few more weeks. adding a few pieces of LR and a light will help to start spreading good bacteria onto your new rock. test this water every few days for PH using your salt test kit. after a few weeks of getting stable reads of around 8.3 the rock is 100% safe to add to your tank.
in the first few weeks of the fresh water bath you may notice an oily film on the surface of the water, its normal. keep changing every few days and it will disapear.
as far as ratio's and ingredients, thats up to you. i used equal parts of portland cement and argonite sand. it hardened like a rock, lol. it's not as pourous as i would have liked but i wanted it to be able to hold up my real LR and need it to be strong. i suggest making a few base pieces ( see pics at top of thread) and use airline tubing of different sizes to create chambers. i did this so pods would have a place to breed and be 100% safe from predators ensuring the population not only survived by grew. i happy to say it worked to perfection. the deep chambers i made with standard airline tubing are only big enough for the bugs to get in and in a few weeks ive seen more pods then ever before. my Mandarin is very happy
