OK, so today didn't go as planned. I was busy all day, but didn't have a chance to look at the skimmer pump. We had a family event planned, but due to a sick kid things changed. Instead of going out, we would stay home and have visitors here. This meant I needed to clean up the fish stuff I have scattered all over the basement. That would include the fold-out table with my planned aquascape on it. I happened to have a table with the exact same dimensions as my tank, so I had it set up in front of the tank - which made things easier. I might have been able to convince the family that I needed to leave the table in place, but decided it wasn't worth the fight and just put the rocks in the tank. I only decent picture I have of the rocks before I started all of this is from above.
I don't like to put the rocks in with water in the tank. It just makes everything harder, but I certainly wasn't taking the rocks apart again. It seems no matter how many pictures I take, I never have the one I need to re-create something after I disassemble it. So, I've come up with a system that works pretty well (for me at least). First, I don't put any rocks directly on the glass. I always put a sheet of acrylic down for the rocks to sit on. This eliminates point loads on the glass, gives a little bit of protection from rock slides, and make it easier to move the rocks around. I try to use big sheets of acrylic, but sometimes have to use a small piece to cover everything. I leave the protective sheets on the acrylic when I'm initially setting things up. Once I get the rocks stacked the way I want, I use a Sharpie to trace around the rocks. I also put a small mark on the backside of each rock. This makes it easier to reassemble everything later. I'm not sure what's in Sharpie, but it probably isn't good for the tank. Since the tank is full of tap water, I'm not too worried since all of this water, and anything that leaches out of the Sharpie marks, will be dumped and replaced with fresh saltwater.
Then, I use a masonry bit and drill to put frags anywhere that I might want to put a coral later. I generally use the "more is better" approach and put a lot of plugs in. If it becomes obvious that a plug won't be needed later, you can always pull it out (or just let the coralline encrust it). When it come time to place a coral, you just pull the plug out and place your previously mounted frag in its place.
Next, I disassemble everything and rinse the rocks. There is quite a bit of dust on them when they arrive and drilling all of those holes makes it much worse. I rinse them well, but there is no way to get all of the dust. The tank will just be cloudy for a while.
Once the rocks are somewhat dry, it's time to put everything back together. At this point, I carefully pull the protective sheets off of the acrylic. The bottom sheet I throw away, but I keep the top one because it has the tracing of my rocks on it. I place it on a flat surface (markings up) and then put the acrylic sheet on top of it. Now, I can see where my rocks go but the sheet isn't stuck to the acrylic. I suppose you could just flip the acrylic over and make a mirror image of your original aquascape, but I don't go that route. The protective sheet tends to wrinkle and stick to itself a little, but it's pretty helpful and I think it's worth the effort. Between this and the alignment marks on the backside of each rock, I've been pretty successful and re-creating my aquascape.
I use putty or silicone to hold large sections of the rock structure together. I bought some small acrylic rods, but didn't end up using them today. I might put some in after I drain the tank. Next, I remove the map from the underside of the acrylic sheet, move everything to the tank, and make any necessary final adjustments. The acrylic sheets make it nice because they slide on the glass and I can move large pieces (or the whole aquascape) as needed. Despite rinsing the rocks well, the tank is very cloudy. Hopefully tomorrow I'll be able to get a decent picture.
Before adding water to the tank, I did my best to clean everything. There is no possible way to get everything though. Since I'm not running the skimmer, I decided to do some mechanical filtration. I probably would have done this even if I were running the skimmer. Anyways, I used a rubberband to put some filter floss on the pump inlet.
Yes, restricting the flow on the input of a pump is a bad idea. It can lead to cavitation, which quickly leads to pump failure. Knowing this, I only left the floss in place to collect the gunk I could see. If didn't take long for the floss to be covered in stuff.
At this point, I pulled the floss off and shut things down so that I could replace it with a new one. I did this a couple of times - until I couldn't see any more stuff floating around in the sump. I'm glad I did it rather than let all of that junk go through my pump. I also put floss on the drain pipes. That should be catching anything that was in the tank itself, before it can get to the sump. If it wasn't obvious, I'm don't plan to run filter socks.
I decided to put the gyres into the tank to help stir up any junk in there. This also gave me an opportunity to see the flow (like one of those BRS videos). I won't know for certain until I have sand and corals in the tank, but I don't think I'm going to need any powerheads. I wasn't planning to use any, but you just never know until you get everything together. I haven't had a chance to play around with the gyres much, but they are pretty impressive right out of the box.
I'm having an issue with my Vectra. The power cable doesn't fit into the transformer well, and it randomly loses connection. Anyone else having this issue? I guess I'll have to contact Ecotech about that.
