Slow down you are going to fast .... The lfs
just made money on you .....I have found that even with a good pet store NEVER listen to thier advice .....They have to make sales , that is their lively hood .That is what these boards are good for we have nothing at stake and need to push a sale ...He is right that it will do fine ...................for a short period, but long term is sucess is not likely...I really think that you are headed for a crash ,,,long term success does not come over nite .... Set up your tank , cycle it the only things that should be in your tank right now is :
Live Sand or sand
Live rock (this is a must)
sit back and wait , your cycle is under way ....
Here is how your cycle will look
Ammonia will rise and fall to 0 . Ammonia is the most toxic to fish and will burn gills.
NitrItes will rise and fall to 0. NitrItes are the biproduct of ammonia less toxic but toxic none the less .
NitrAtes will rise and fall you will then do a water change at this point to drop them to lower than 20 .... This is the biproduct of the Ammonia breaking down to NitrItes, NitrItes then go to NitrAtes it is still toxic but less so than ammonia or nitrItes ...
Ph should be steady at 8.2-8.4 will be higher with the cycle of lights .
Spg should be at 1,024-1.026
Temp should not have huge swings and be at around 77*-80*
The cycle can take any where from 2-6 weeks to complete ...No fish are needed to cycle die off from the LR
is enough to kick start it if not add a table shrimp (unseasoned ) All you need is die off to start it .
Once complete you can add a CUC to help with the algea that will be there (also a biproduct of excess nutrients and the cycle )
You are headed for a crash and I dont want to see that happen ... I have been where you are I wanted it and I wanted it NOW trust me it doesnt work like that . I advise you to keep all reciepts and log them to see what kind of money pit this can turn into if you have a crash..I can see you becoming fustrated or even broke trying to "fix" the broken tank that could have been prevented from the get go ... You ask for advice but ignored what was given ... I dont want to see you think this hobby sucks due to failure ....But you are moving far to fast to have long term sucess , short term perhaps but long term not at the rate you are moving ...Please dont make the same newbie mistakes I made , these boards and folks teach from experience of what works and what doesnt ...
