| | Re: Staghorn Algae ? and advice
The staghorn algae shows up when there is a spike in Ammonia. Reducing the Nitrate to an actual, real 0 for a few days usually makes it disappear. This is what has worked for me every time. Some people actually suggest raising the Nitrate levels but that is not my experience.
I'd say start changing 15% of the water every other day. Your goal is to reduce the Nitrate to 0 for a few days. Don't test for Nitrate - test kits provide inacurate, barely useful snap-shot picture of the parameters, calibrated or not. Make sure you use water that will not impact the bacteria negatively or you will be shooting yourself in the foot. I suggest using water ran through activated carbon, not just dechlorinated. If you are cheap and don't want to spend $40 for an active carbon water filter then use only Seachem Prime, all other dechlorinators are inferior.
Remove all dead leaves, all staghorn that you care to remove, don't feed the fish, vacuum with an air tubing if you have to. Basically keep absolute hygiene and frequent small water changes for about a week - minimum organics is your goal.
Staghorn does not care about the flow. I've had it explode in a very low flow tank, and my neighbour had it develop in a 75 gal. tank with about 800 gph total actual in-tank flow. In both cases frequent water changes and better hygiene lead to the staghorn demise.
