firstly, do you have a skimmer? which i think shd be the basic. next do you have test kits? if not how can you tell the water parameter? if you wanna test your water bring maybe 100ml of your tank water to my house. i help u test. dun rush tru the process, easy to say as i understand hw u feel. but at least make sure ur water is ok. did u use MP or BB kick starter solution? if you use them the process goes sumthing like tis.
Ammonia - NO2 - NO3 - spike - down to maybe 50 den u know u need to do WC. then wait for mayb 1 wk den test if the water is like 0-25. u are ready.
hope this helps...btw, sames goes to FW also
