    How old is your tank. 29 is not that high. Ive seen some tanks using ro with that readings. All over nature gha grows. There is just fish and urchins etc. grazing it and keeping it under control. And remember when there is gha the phosphates are trapped inside them, when they die off they release this and the problem keeps on going. And it aint a lost battle but do you run a phos remover? How is your lighting regime ? What cleaning crew do you have in your tank ? Things like these can make a huge difference.

    Max already asked a few very important questions especially on how old your tank is. Like max said hair algae trap the nutrients by using them. What is the amount of flow in your tank, to little flow can cause detritus to settle and then turn into nutrients, then the nutrients are used so fast that it doesn't show on the readings. Also try to run your skimmer on wet, also what skimmer and other filtration's are you running? Also you can try to uplift the sand to release any trapped detritus to flow into the skimmer. If all of this still doesn't work then you should think of an algae scrubber, very easy to DIY just search the DIY forum.

    hey bra the drinking ro unit is incorrect,you need to rather contact Marco at water boy and get a ro unit for marine tanks,as the filters they use in ro water drinking units will cause a problem and that all depends on the filters been used,and a tds of 29 will cause a algae bloom

    ok thanks for all the comments.....

    the tank is almost a year old. i have quite a bit of flow... 5000L, 6000L and 4000L powerheads. had a scrubber...it broke..going to make a new one. have a fuge in my sump on the DSB with chaeto and caleurpra. @Annoying: i think ur right about the readings coz my phosphates have been 0 for 2 months.

    im going to add a deionizor to the RO unit so i can turn a tap and the water will skip the the mineral chambers and go through the deionizer instead... i hope all questions were answered. now we can come up with solutions :)

    Could you maybe post a pic of your tank and engine room? A pic always help, maybe we can see something you have missed.

    Robin, like I said this morning its almost certainly caused by collecting your NSW from the Aquarium. All the other guys who have major GHA problems in EL at the moment have been collecting from there. Change your NSW source and I think you will go a long way to curbing the problem.

    Did you use reef booster and then had the bloom? could be the cause.

    How are the new fish. that bi colour looked great, and the clown I think are stunning.

    dude do you seroiusly collect from the aquarium?

    irrespective of where their water is pulled from (the shark pool or the sea) it is pumped over the road and particle filtered through a french drain system, id hate too see how much kak is rotting in there, i would even suggest rather taking water direct from the sea than from their facility..

    its sad but true..

    if in an emergency you somehow have to collect there allow the water ro run for a minute plus before putting it into your drums.. the water in the pipe lays stagnant and becomes anoxic creating hydrogen sulphide, thats the smell you are smelling..

    1. small petrol pump with long pool hose connected
    2. bakkie with nice big container on back
    3. a lekker drive to yellows mouth when the tide is pushing ;)

    husgavana in cambridge you looking at approx R2500 for the pump couplers and hose will set you back another R500 - R700, an inverter and a normal 3000lph or 4000lph pump is cheaper, would cost approx R1k to set up, just connect to your car battery and you a 4 away

    Buy a 25 lt drum, go to parking in front of Gonubie hotel, R 20 in hand, pay the guys doing car guard, they will fill it for you.
