Anyone want to learn advanced rockwork techniques?

I agree about the video, I'd love to see this but can't make it over

Further to my interest, here are some questions that come to mind
and could be addressed either with post-event pictures or forum posts.

-Do you use PVC shed 40 and paint it? If so, what paint & cure time?

-How practical is it to work on rocks being pulled from the tank
(and that have some life on them)?

-It looks like you use some sort of cement/mortar to mask fasteners.
If so, what is it and how long a cure time?

-Would be interested to clearly see a frame before rocks are attached.

Perhaps others can submit questions ahead of time?

Video or pictures are fine. I think that the latter is easier to produce
and therefore more likely to be volunteered for...

In these pictures, I've used both 40 and 80. I don't paint, but that's not to say you couldn't use Krylon Fusion beforehand (cures reefsafe IME). Cure time is as per manufacturer's recommendations.

Pretty easy. You lose your coralline often, but it's a minor nuisance at worst.

Just regular concrete. I cure in tank once it sets up if there's less than ~1 cup/100 gallons of tank volume. If there's substantially more, I cure for two weeks remotely. Ideally hydrated for max strength.

Here' are a couple I have:

Albert,

Thanks a lot - these are quite helpful.

I'm a bit hesitant to work on existing rocks (as this is all I have) and
cure concrete in my tank so I'll have to think this through some more.

Good luck with your presentation

Cheers from the Okanagan,

I'm going to try to make it tonight
