A couple things...
Anyways - Tonight will add More Live Rock and mix up the sw for the pwc.
Whoa... I'd hold off on mixing up the SW
for the water change. According to the water parameters you posted yesterday, you still have measurable ammonia AND nitrites... and fairly good quantities of it. I'm guessing your nitrites haven't even peaked yet. Not sure when you started the cycle, but I'd say you have at least two weeks until your cycle is done. Doing a PWC
while you're cycling will take away the ammonia and nitrites that those bacteria need at this point. No PWCs until the cycle is complete - unless your ammonia goes sky high, but that doesn't seem to be a problem.
Also... if you're adding uncured live rock and there's any die off from the rock, this will again boost your ammonia levels. Just be aware of that as you're adding rock and checking your parameters. If that happens, it just means your cycle will last a little longer. But if you're going to add more rock, I think it's best to do it now rather than wait.
To test the tap water should I mix up a batch of SW in the bucket and cirulate it for a couple of days before testing or can I test the water straight out of the tap? I ask because my Masters Test kit says its for SW only...
Assuming it's the API test, as roka64 mentioned the ammonia/nitrate tests are good for both SW
. The only difference is a slight variation in the colors at some of the levels. I believe the "Saltwater Master Kit" only comes with the SW
color cards - so they kind of mess you up for using it on freshwater. Buy the tests individually, and you get both FW
color cards. Go figure. BUT ANYWAY... you don't need the FW
cards because you're looking for ZERO levels for both ammonia and nitrates and the colors at the low end are pretty much the same for both FW
So... test the water straight out of the tap. Just be aware that there can be other nasties in the water too. Phosphates are often in there, and will cause issues with algae. Depending on your plumbing system, you could have minute amounts of copper which over time could accumulate. (I know some salt mixes have stuff in them to "knock out" the heavy metals, but I don't know if they all do.) In addition, even if your tap water tests OK right now, it doesn't mean it's going to stay that way 6 months from now. I learned that one the hard way. I'm not saying you have to use RO
water or buy distilled water, I'm just saying you should be aware that your original water quality will dramatically impact the health of your tank and that you should know up front what all you could be putting in your tank.
And regarding feeding, to expand on Roka's point, once you settle on a stocking list, that will determine what you feed. Some fish only want meat, some only what veggies, some want both. It all depends on the fish you plan to keep. Now is a good time to think about what you want to keep - and research to make sure that your inhabitants can get along with each other.
