As others have said, I reiterate, do not use meds on the tank. Increase skimming, check food source and amount, check filtration, boost natural copepods and amphipod levels, and increase tank flow... and don't forget checking the water you are using.
What if we have done all these things you have suggested (plus replace the light bulbs) and still, nothing. All my water parameters are fine, and everytime I manually remove as much as possible from my tank, it comes right back. What justification could you provide for being so adamantly against the meds? I don't want to put anything unnatural in my tank, but after weeks of trying to get rid of this problem, I am about ready to give in.
first, patience,-and don't panic :mrgreen:
first explanation-if you truly did get rid of/correct the conditions that cause a cyano out break-you wouldn't have any.period.the very existence of the cyano prove that there is still something in your system that is fostering it's existence.
what you need to understand is, that the foodstuffs the cyano needs may still be present, and being consumed by the cyano, even if you show a zero reading on a test kit.in other words-the production of PO4, and the like, may not be getting a chance to accumulate in the water column, in order to show a reading on a test(.01ppm PO4 produced, and .01ppm PO4 fed upon=cyano growth with a zero test reading :wink: )the trick is to establish a NEGATIVE trend in the nutrient production-to starve the cyano, even beyond a status quo of its existing w/out spreading.
also-if you use an antibiotic(the only med. that is specific for a bacteria, like cyano)-the following will happen-the cyano, when it dies, will re-release the nutrients it has absorbed back into the water column, and the antibiotic itself will add to this, and then you're back to square one, to eventually deal with the cyano again-only this time, it may be resistive to the antibiotic.
see the trap? :wink:
i'd suggest the following tack:
first-the easiest way of removing the cyano's nutrients is by removing the cyano mechanically(
siphon it out, don't net it out-this will break off little bits, that will help it to spread.
second-use a PO4 removal product, like phosguard,and change it frequently(small amounts-1 tbs/10 gal.changed every 3-4 days)to make sure there is no 'dead time' in it's removal function.
third-if you use carbon-test it with a PO4 kit-most carbons will leach PO4 into the water.if it tests positive,-don't use it!
fourth-be absolutely sure your source water is
perfect-and be absolutely sure you have no uneaten food
anywhere in the tank within 5 min. after a feeding.
fifth-use kalkvasser-it helps precipitate the PO4 out of your system
sixth-be very patient-it may take a month or two, from today-but i promise,if you ensure a negative to zero accumulation of nutrients, and remove it religiously, it will go away,
it has to.
hth, and best of luck!
keep us posted.
what are your NO3, and PO4 levels, and which test kits are you using?
