Overhaul Time

No prob.. now back to the thread subject.

Keep us posted, I'd like to hear how this goes in something near to a step by step... we all have one of these in our future if we stay with it.
 
I have already taken most of the sand out so I might just take the rest out and go bare bottom. If I were to replace the old rock with new I could stick some of the old rock into the sump to help out with the bio filter.
This tank was set up a long time ago when the norm was 2 lbs of rock per gallon with all the flow you could muster. I had a deep sand bed ( 8 inches) in the sump and very few hard corals. Some of this rock is so old it was collected off Fla when it was still legal to do so.

That Fla rock was typically very dense too - also figuring into the lbs/gal recommendation of the time. In all my recent experience with live rock (mostly Pukani, Fiji, Jakarta) 1lb/gal is usually way more than enough. I mentioned in another thread (maybe I'm repeating LOL) that when I transitioned from my 38gal to my 50gal, my rock was pared from about 40lbs down to what I'd guess to be around 10lbs. But this rock has massive colonies grown on it (see this post for example pics of the current layout) which may be factoring in as live rock at this point, and I keep an extremely low bioload. It's now basically just four chunks of live rock "scattered" on the tank bottom, if you were able to see it without corals I've grown.

If you're running a heavy fish bioload, it's possible you could still use some of the "extra" rock in your sump, but then you lose sump space and don't increase water volume which arguably could be more valuable. Can't say what's the right way for you to slice it, but it's all worth considering. I think I'd test it out with the "extra" removed (which you will keep "live" for a while in a tub or something) and just be observant for a few days. It wold be an ideal time to use one of Seachem's AmmoniaAlert submersible tests, just in case things don't work out you'll know before anything can go sideways. OTOH if that's too much maintenance...

It should go without saying, but definitely space out your removal of the rock over at least a week...2 or 3 weeks wouldn't be too long. Have your AmmoniaAlert hanging at the beginning of the process.

Your call man! :-)

After two months I have made some changes.. New skimmer and return are here. The new sump will be done next week. I have replaced most of the rick with new. The old rock has made it to the sum for now. Next thing on the list is to clean everything "like mom was comming to visit'.
Please let me know what you think of the aquascaping. Please let me know what I can do to make it look better. I am so used to THE WALL that I am not sure if I like this.
Thanks

Fairly ncie scape with plenty of nooks and crannies for fish to hide in and what have you. But man oh man is that pvc an eyesore. Anyway you can yoink it and maybe spray it black with krylon fusion? Would help it blend into the background more.
 
I pulled the PVC out and the rock on the right side. I ordered some 1/4 inch dowel that should be here the end of the week. See how it goes.
