Looks good all around, it will look crazy until the rocks color up to match. You sure you have the pumps on S1?
Tank is coming along well and I love the aquascape also. Hve you thought about using some putty over the pipes and adding rubble? Just an idea.
What type of putty do you use? Its a great idea.
I used a two part and putty on my aquascape. With the putty you can use rubble rock to form shapes and it kinda makes it look like a sponge. With the two part I use rubble and the dust from breaking the rock to apply on the two part.
Do you think I can do this with the rock still in the tank?
If you use aquastik you can knead it in your hand and apply it in the tank, then add bits and pieces of rubble to it but you will have to wait about 4 min for it to start to harden. Of course it is easier outside of tank.
I usually order my aquastik from amazon for 10 bucks with free shipping and the frag plugs I recycle from frags I have bought. If course after I dip and soak the plug in fresh water.
Suggestion, if the black ones are plastic cancel them and get the ceramic or stone ones, not sure what they are made of. Anyway the plastic ones are much thicker at the base opposed to the ceramic ones. What you can do with the stone ones is drill a small hole in the rocks about1/2 inch and slide the plug right in. I think the plastic black ones are 3/4 inch think and need a bigger hole. Also some most porous rock already have 1/2 inch spaces and you can work the stone plugs in without drilling. I like doing this because I can not only rotate the coral in the same spot if you want to change where the light is hitting it and if you want to swap it's location you just pull it out of the hole and pop it in another.
Just a suggestion
