Humm, maybe we're mincing words here or I'm not seeing the picture correctly... When you refer to bubble box, what are you referring to?
What bit isn't fine? nothing else is adjustable ?
As the waste breaks down it is processed by the tank filters from ammonia to nitrite and then nitrate. Some nitrate will be consumed (occasionally all) but then there are other pollutants being released which affect the tank in other ways, such as calcium, Alk and phosphate levels. Water changes help keep your levels more stable.Ooh thanks, na i wasn't trying to avoid them, just researching weather i needed to buy more water for physical water change aswell, but surely fish poop would sit at the bottom and water changes would be form the top?
Ok another question, Ive had my tank up and running for 2 weeks now, the water levels are fine, but ive only got 40kg of live rock in my 130 litre tank, do i need more live rock before i can introduce CUC
