I was jsut wondering about how you guys do waterchanges with large tanks. For those of you who have tanks of a few hundred gallons or more, how do you do waterchanges. Do you find u can get away with changing lesser ammonts of water at a time or what. I mean i do 30% waterchanges on my 90 weekly and i was thinkign ok well thats around 30 gallons there, what do you guys do with big tnaks were a 1/3 % waterchange woul be like 150-200g or more! Or do ypou all have these tnaks on a drip system, or do you have to do ltos of little changes? please let me kno what you do, imvery curious because i want to venture into larger tanks soemtime. Thank you.
