  • Truck drivers can have fish tanks too. Im sure your a marine bioligist. He makes a good point about refugiums.

  • He is the first person after asking so many people that was actually able to clearly explain to me what a refugium is.

  • @quaqa88 i agree!

  • Water changes only solve half the problem, but consistently high nitrates can be a sign your bioload being too high for your biofilter to handle. the best way from experience is to use a combination of seachem denitrate media and chaeto macro algae along with a chunk of live rock in a refugium. chaeto will absorb excess nutrients and the denitrate will lower nitrates by anaerobic filtration. weekly water changes are also key but a stronger more efficient bio filter will be the best way to go.

  • actually there is a very good media out there to lower nitrates it is called bio pellets they use bacteria to lower nitrates. and EXMR84, high nitrates does not always mean a bad filter. nitrates can be caused by death of a fish or inverts. however when it comes to lowering nitrates there is nothing better than frequent

     water changes and a refugium

  • @EXMR84 obviously the water flow is slow almost drop by drop

  • @EXMR84 how? I have a external filter, loaded with coral sand of different size. Starting with bigger size and ending with sugar size. I "feed" the bacteria with on spoon of fructose every morning and evening.

    Before studing the nitrate problema I had 50 mg/l now I can't detect the nitrates

  • every time i hear talking about Nitrates Reef Tank I hear a lot of bullshit! the Nitrates are part of the azote cicle. If you have nitrates it means that you have not a good filtration. A refugium can for sure be useful, but , for me, it's not enough . You have to let the anaerobic bacteria work! that's the trick!...!

  • WOW, I'm impressed!  These videos usually suck.

  • finally expertvillage got something right! :D

  • I think he's very sexy!

  • @Vaun686 Yeah I beleive he probably does but a 1:40 video on such a complex subject is a joke.
