okay so my girlfriend went to the local aquarium store and got me a bunch of stuff to convert my 55 gallon tank to saltwater. so i went and talked to the owner of the store and he told me everything i needed to get it up and running, but now after reading alot of articles online, i feel like he really didnt explain everything to me and i might have made a huge mistake. i already had an emperor 400 filter, and i got another tetra whisper ex45 filter. i also got a new 200 watt heater and a hydrometer. as far as chemicals, we got bio-spira, stress coat, and pro clear. so we put in the sand and the water, and mixed the salt. the next day we added the stress coat, pro clear, biospira, and a couple hours later we put in 20 pounds of live rock and 4 damsels. this was all by the stores instruction. its now 2 days later. after reading online for about 4 hours last night im finding myself extremely overwhelmed with all the information about cycling. i didnt even know what a cycle was until last night. i guess my main question is... now what? should i just let it go and see what happens? or should i start over? what should i expect to happen? if anyone has any advice i would really appreciate it. thanks.
