    Hi guys -

    So my tank has been running for about 10 months now.
    I have never had a single issue with algae but all of a sudden it is haunting me!!!
    Phos is 0 and nitrates are 2,5-3
    Im running a phos reactor and a nitrate reactor.
    Photo period is from 8am to 7pm
    I feed ocean nutrition twice daily with garlic guard and amiomega (brightwells)
    I dose zooplankton twice weekly and feed frozen to fish and corals about once a week.

    I also dose KH and Reef complete twice weekly.
    Lighting is quad 54watt T5
    Running Ts2 skimmer
    Mechanical filtration - sponges in sump
    Flow is good

    I have a sand sifting star that takes care of the substrate but cannot keep up with this onslaught!

    Any tips or recommendations would really be appreciated!

    I think you might be overfeeding. Also how old is your unit's bulbs?
    To help bring down your light period as well

    How much would you recommend- difficult thing is they only come out when lights are on and therefore feed only when lights are on..hence feeding 8am and 6 thirty odd pm. It also sucks having a tank that you never see with the lights on. Could one have a photo break during the day?

    Algae? Looks like Diatoms or Cyanobacteria.

    Definitely not diatoms. Theres a fair amount of gha on the lr. As i understand diamoms is almost like a dust everywhere? This is actually causing the substrate to stick together in places. It is almost stringy. Cyano? If so options please? Im all for reducing photo petiof but will it be ok to do this during the day for 3 hrs or so?

    Think it shouldnt be a problem. What filtration are you using? Is it a red slime maybe?

    Its not a red slime- its more stringy and brown and slightly slimy id say. I have 2 chambers of sponges in my sump, matrix and phosguard in filter bags, t2skimmer, and in last chamber i have lr and return pump

    I think you might be incorrect in your thinking. Diatoms can be quite thick and does clump together. Not always a dust.

    Anyway both Diatoms and Cyanobacteria are aggravated by low DO. Also high Si and PO4.
    Look at increasing flow and elevate Mg a little.

    A 48 hour black out might also help.

    Dissolved Oxygen.

    Normally in the colder months reefers close up their windows and doors which results in a CO2 build up in the house. This does not allow for an efficient Oxygen to Carbon dioxide exchange.

    Si is silica. If one adds Si-O we get silicate. It all forms part of the redfield stoichiometry.

    Just on this, if ones silica or silicates are too high, how does one reduce them? Purely through the use of 0tds ro water?
