9 footer disaster

It doesn't appear to be Spafle. Here is what spaflex looks like:

Looks like it's the tubing for the Reefmat which is very thin, but I've never had issues with it leaking. Also, I've always been under the impression that a tube should be installed over a pvc/barb, not slipped into fitting or pvc. I think for my Reemat I slipped it over a 1" pvc and used Fusion pvc cement with a hose clamp.

Need help to aquascape it. Suggestions please.

Not that lol.

But seriously, pick up some of the mortar that @Coral reefer uses and make some mixed rock structures (some flat pieces mixed with branch to look more natural. The benefit of your 9ft tank is that you can have dramatically different zones e.g. a sheer face (anthias, damsels) vs. a rubble zone (wrasse friendly area).
 
Reminds me of Stonehenge :p I think you might need more rock .

Btw: if you only try to make little caves intentionally, it's easy to end up looking like mcdonalds arches. Discrete, individual stacks looks sort of unnatural, especially in a tank like yours where a single "arch" doesn't even fill that much space.

You can try making 2 mounds (plus some islands), with one slightly taller/larger than the other, to create a diagonal line that the eye can follow. Start by laying a base for each mound and then layer upward, leaving gaps to become caves. Make sure you have forward-back depth so it doesn't look flat from the front. This is what I did with my tank

I think that big tanks are a little harder to scape overall though, since a lot of rock comes in kind of round shapes that look funky early on. You can always try chop with chisel
 
A couple of basic aquascaping principles I've learned that make a big difference:
  • Right angles don't look very natural, avoid creating square looking things.
  • Try to apply the golden ratio for positioning and spacing things on "third lines." For example, if you have a focal point (maybe a break or open space in the rockwork), place it 1/3 from either end of the tank. You can also use this for creating rock structures of different heights.
In the end, it's all preference. If you like it, that's all that matters. The guidelines above just help create something appealing to most people.

Any clear examples of what u mean by 3rds I kinda follow but don't think i see it in my head.

The rule of 3rds is a simplification of the golden ratio. If you divide your tank in a grid of 3rds, intersections of lines are good places for "focal points," or things you want to draw attention to. Could be a break in the rockwork like below, or some other visually interesting element.

Thanks that makes it clear

In landscape, architecture, interior design ETC. it’s called the rule of odds. Makes things more dynamic and aesthetically pleasing.
