So...lost a couple of monti cap frags and the dinos came back after the water change. I guess I can't really complain though, because it is such a manageable level and I've seen what other people have to deal with when it comes to dinos.
I did a 50% water change on the QT and also siphoned out whatever dinos I could see from the DT.
I'm going to keep doing what I'm doing, sans water changes on the DT, for a while. I need to get some CO2 tubing in order to get the Ca Rx running. I'm going to try and go without a water change until I add the next round of fish to the DT (so, like 10 weeks). I'm not going to add any more frags until I do that water change and see if the dino's come back. If they do, then I'm probably just going to replace all the rock and sand, clean out the system, and start over.
In the meantime, I'm going to get those VorTech QD drivers and upgrade the lighting on the QT in case I need to move the frags over while the new rock and sand gets cycled.
I usually do a large purchase for this hobby at the end of summer, when my fair-weather hobbies are winding-down and I'm getting ready for winter (aka fish tank season). I'm hoping I don't need to tear the tank apart and start over. Since I don't really need any equipment, I'd like to take that time to add a bunch of corals and sit back to enjoy this tank for once, LOL.
