if i were to add the water from a smaller tank to a tank about 50g's bigger with the fish and everything would my tank have to cycle all ver again and would it be a bad one for the fish?
You will still find that your tank will go through a cycle period, not as long depending on the upgrade in gal, but nevertheless, you will have a cycle.
ok and i would be adding 50 new gallons water.. so you think for the most part the fish will be ok? b/c unless i put them in with my shark which wouldnt be good then i have nowhere else to put them.. and so if i used my old filter and protein skimmer at first.. i could just add my new one on later on? im actually thinking about getting a canister filter and using my old hang-on-back and the canister both.. not sure yet.
oh sorry one more question.. i know carbon is bad to run in filters.. but it comes with the canister filter i got.. is there anything i could run instead? or should i just not run anything in its place?
Do you have an established sand bed and liverock? If so, just transfer them over. I did this when I upgraded with no problems and no noticeable ammonia/nitrite spikes.
