So I don't have money right now to get a real reef lighting system for my tank. I have two 4 foot fluorescent bulbs (they are just standard aquarium bulbs) , will I see the colorful algae growth on my live rock?

so my tank is 62 degrees, so i guess ill go get it! thanks!

How cold in your opinion would be too cold?

No my heaters are arriving in a week or two, and I won't be able to get this rock unless I buy it in the next few days.

The water is probably in the high 60's. I might be able to get it a little bit warmer but I only have a very small aquarium heater

So I found a good deal on some live rock, but I don't have heaters in my tank yet (they will arrive in a week or two). Is live rock alright to keep it in cold water, or will this kill all my beneficial bacteria?

Alright thanks alot this is all really helpful!

How many powerheads do I need for a 90 gallon reef tank? I understand that the water needs to circulate like 15 times, but I dont know how to figure out how many power heads I need. If I had two 350 GPH powerheads would that give me 700gph circulation? Is that how this works? Add up the GPH's...

All I have is water and substrate. I'm going to be using the cocktail shrimp method.

So I have ordered a lot of the equipment I'm going to be using for my new tank online. I am waiting for most of it to arrive. I was wondering if I can start cycling my tank before I add salt? Or does that screw it up some how?
