Add more base rock to established tank?

[Sophie"s mom]

Good afternoon everyone! So as the title implies, I am thinking I might want a bit more rockwork in my tank. It is a 90 gallon, been set up since September last year. It is pretty well established now, and has about 50 LBs. of base rock which is or course now all live rock, as well as about 30 pounds of live Jakarta rock. I an thinking I might wat to build another cave or 2, and of course base rock is MUCH cheaper. Can I do this with about 10 pounds of rock? Or would be too detrimental to my tank?

I do not think it would be detrimental. What are you concerned about

it wont hurt your tank if the rock is clean and fine. I've done this to get more real estate for mounting corals when i had a 75

Watch your phosphates. I added about 7lbs or so a week ago and it is just now starting to stop sucking up phosphates. They kept zeroing out and I had to keep dosing phosphates daily, but it seems to be slowing down now.

Not concerned at all, just wanted to make sure I didn't need to be :smirking-face:

Good to know, this would definitely not have occurred to me.
