What could I do?

Well, back in the day when I started my tank, I didnt know much or any about salt water tank, I used about 10lb of live rock, and 20lb of river rock to cycle my tank, with 20lb of really soft fine white dead sand.

As I finished my cycle and my tank went along, I found out I wanted ocean rocks rather then river rocks in my tank *lol*, after looking at 3reefs members pictures my tank looks like fresh water tank, hah..hah
but I have no problem with river rocks at the moment, all the water parmeters are fine and such, but I just dont like the look.

Also I kinda dont like the super fine soft sand because they float around and make sand storm just by water current if I dont place my power head all the way facing up, Is it too late to replace the sand? if not how could I replace the sand?

Well long story short, could I change all my river rocks to ocean rocks? like maybe add live rock and take out the current rocks I have?
And is it possible to change the sands at this moment? the tanks been running for 11 months now.

I cant find my cameras computer connecting wire, so I ll just have to use the pictures from october.

You can change everything out slowly if you desire. Just do a small amount at a time. If you get live rock you will need to season it, put it in a container of salt water with circulation until it cycles before adding to the tank.

 

I'd get rid of the river rock. Rocks formed in the earth may have high levels of metals that could leach into your water. You can change your sand bed but if it were my tank I'd only do it a pound or so at a time over the next few weeks, especially if the tank has already cycled.

 

+1 with above post

 

If I were to use dead rock, could I just take out all the river rock and just replace the whole thing at one time?

 

No. You can use dead rock, but understand the function it serves. Since rock is media upon which nitrifying bacteria can grow, then removing all the river rock would result in more ammonia, nitrites and nitrates than the bacteria can handle. If you add a piece of dead rock, then wait a week, then remove a similarly sized piece of river rock, and proceed thusly until all the river rock is replaced, then you don't throw the equillibrium out of balance.

See?

A "balanced" tank you sometimes hear of is simply a system where the population of bacteria is sufficient to process (nitrify) the ammonia and nitrites as they are produced--meaning these three compounds don't build up to toxic levels (nitrates aren't considered toxic, but it's great food for algae).

Here's a bad analogy. You can't remove your liver unless you have another on hand, ready to replace the one you yank out.

Finally, you should know that ocean rock, or live rock (as it becomes if purchased dry) is thousands of times more porous than your existing river rock--which is smooth and lacks porosity. Replacing your river rock with ocean rock will help you immensely. And. .. your tank will look less like a lake, and more like a reef.
