You guys make it sound like my tank is a cesspool when they are as clean as can be. There is never an accumulation of any solid waste. Maybe you feed your fish too much.
I do think that's excessive because its probably unnessessary. I do think it more likely that its a person's over attention to their hobby than a case of finding it to be a requirement. If it is a requirement, then as a fish enthusiast you must admit something is wrong with the setup to require that. Either its massively overstocked or something...
I have a drip system on my other tank. We're talking about manual water changes here... but yeah, the same rules apply. I'm thinking about tappering down the drip factor based on readings... but only after I used my goldfish as a test first. My 2000 gallon is massively understocked.
