    Hi All

    I need some advice with my tank.

    20140414_184701.jpg

    I have both Cyno and a brown algae growing on my substrate. What is the best way to deal with this?

    What lights you using? If T5's, how old are the tubes? I use reefktek T5's and found after about 4 months the cyano comes back with a vengeance until I change the tubes.

    go to the pharmacy i had the same problem with a dying seastar behind the rocks. purmycin capsules 1 for every 30 galons of water. empty capsules in ro water2l coke bottle, skimmer off for three days after that no algae(bacteria). really works and dont harm fish or corals and cost about R5 for 5 capsules.

    cyno is a bacteria not alg and purmycin is a bacterial treatment.

    You mean an antibiotic? A schedule 4 antibiotic? That requires a prescription to purchase? Makes sense to me

    Treating gram negative or positive? And what effect on other bacteria / microbiota.
    Chemical treatment does work, so does changing the bulbs, at reducing the visible appearance of cyano... but does it do anything in solving the underlying issue?
    Rather tackle the root cause, ie nutrients and flow and the symptoms will disappear with the cause.

    like irvie said is the best way to go , find the cause. ive have syphoned it out for a month with daily water changes 30% nothing helped. eversince the purmycin, i think it is the generic of eurothromysin. not sure about the spelling. 3months passed without any cyno.

    You are probably not going to like my answer, but if you want to sort it out, let me know and I'll walk you through the process.

    By going this route, does the antibiotic not kill the the denitrifying bacteria ?

    @nudibranch.

    Please give a breakdown of your current filtration and parameters such as Salinity/SG, alk NO3 and PO4.

    Sorry for missing that..... Don't know how often those things are updated. It simply is a nutrient problem, Both NO3 and PO4, but specifically PO4.

    For starters, remove the sand by means of 20% water changes per week. Keep the removed sand in a bucket should you really want to add it at a later stage...:(

    Are you running the cubes via the bomb method? Age? Quantity?

    Are you running any GFH?

    My tank is 350L with sump volume. I'm running the bio cubes via a bomb method. The are 5 months old and added 500ml.

    GHF?

    Remove the actual substrate?

    Yes, like i said, you not going to like what I say ;). But you want that red stuff gone right?
    From the parameters and pic, your sandbed seems to have reached its nutrient sunk overflow point. You could of course leave it and add those pills;)
