    Hi Guys,
    I have noticed that my Chaeto that is floating above my DSB has collected a bit of floating algae or detritis. Should I remove this chaeto and rinse it off in a separate container of sea water or just leave it? I have also noticed that it does not seem to be spreading out across the surface of the dsb but rather growing thicker downward towards the sea sand floor, is this also normal?
    Cheers

    If you don't have flow "moving" the algae, then manually turn it once or twice a week.

    Not necessary to rinse it.

    Naturally it grows as a "ball" it won't want to spread unless you force it to.

    Don't worry Shane - mine does the exact same.... I just turn it - very now and again - as Warr suggested.

    Hi Shane. Some guys prefer leaving it, others prefer rinsing it out weekly to remove excess detritus that may cause nitrates and phosphates. I prefer to rinse it out.

    i would suggest that you rinse it in your old water when you do a water change that stuff can really build up over a while and could contribute to phos etc the same way that trapped detris in LR or gravel would.

    Thanks for the reply guys,
    As can be seen from my tank pics, I am battling with hair algae and was worried about the detritis buildup.I have noticed that since dosing kalk that the hair algae is receding and now the detritis buildup in or on the Chaeto would create more of a problem.
    cheers

    Kalk helps in removing phosphates, that is why the hair algae is dying off.

    Would it be advisable to strain the water after rinsing the chaeto and putting it back into the tank. I am thinking about all the copepods etc. if any in the chaeto.
    Cheers

    this is interesting, do you know that the kalk bonds with the po4 and it settles as a dust type thing, hence removing it from the system, the PO4 is still there but its been effectively been removed from the water column, and can then be removed from the system via WC, interesting little thing hey?

    I wouldn't put any of that stuff back into the tank, anyway by the size of your DSB theres plenty of other space for them pods to live.

    Generally speaking most reefers dose kalk in the following dosages 2 teaspoons of kalk mixed with 1 litre of RO, if the kalk is bonding with the PO4 then should we not dose more kalk. What would the effects be if I was to dose 4 teaspoons of kalk with 1 litre of RO?
    Cheers

    Remember, skimming and water changes will remove the phosphates the the kalk has precipitated. If that is not removed, it will leach back into the system.
    Effects of too much of Kalk will be a very high ph, Ca, and Alk. So dose and monitor.
    Ca- 450 (max) ideal 380-420
    Alk - 6.8-8.5 DKH (10DKH max)

    yes sorry i forgot to say the skimmers would remove the precipitate. You only dose more ca when your calcium level is low, so you need to test for it, you cant just add kalk, you also need to know if your tank is meant to take that 2 teaspoons of kalk as it is before we even start talking about increasing it.
