I change the coral monthly in my HOB's because they start to look like this. And even with multiple filter cleanings they continue to look like this. Doesn't help when trying to combat trAtes with today's overstocked Cichlid tanks. I already change water every 3 days and a sand vac every day in between/on wc's. some say I'm obsessed, I blame it on my OCD![]()
I understand.... but you are using crushed coral for it's chemical makeup and not appearance. You could just take the bag and wash it under some water to get rid of the crud.
As for combating the nitrates, crushed coral has no effect on nitrates to my knowledge. It's only real effect is on PH and hardness. If someone told you different, I'd be suspect as it doesn't make sense. If your tank is overcrowded and you can't keep the levels in the 'normal" range, I'd seriously consider either a change in your water changing routine, a reduction in fish load or the ultimate answer.... a bigger tank
I see a common theme with most of today's fish keepers and that's overcrowding. You guys are working WAYYYY to hard by keeping your tanks overcrowded. I spent less time working on mine and more time enjoying watching my fish. (And I was up to over 20 tanks, fresh and salt, in my house which did not include my hatcheries.) Just something to think about.
