I Had been battling algae for a while.
2 orders from reefcleaners did not really work.
3 day black-out worked some but it didn't remove it all and alot of it just came back after a week or so.
Phosphate and Nitrates were 0 (being consumed by the algae)
I Didn't really want to try Vibrant, nopox, etc.
So, during a water change, I removed a few rocks at a time, sprayed them with 3% hydrogen peroxide, waited a few seconds, and then pressure washed the rocks with an electric power washer (gas ones might be too powerful for this).
I then dunked the rocks in one bucket of old water, then soaked them in another bucket of old water for a few minutes, shook the water off, and returned them to the tank. I left the few rocks that had coral or anenomes on them, alone.
It has been over a month and my tank is algae free!!
Even the rocks that I did not do this too are algae free. My tank has not looked this good in a long time!
I also built an algae scrubber from an old HOB filter, a grow light, a plastic screen, and a take-out container for a cover. I've been harvesting algae from that, but again, no algae in the DT!!
Phosphates are now 0.14 (Hanna)
Nitrates are 2.5 (Salifert)
Your results may vary if you try this, and it may seem a bit unorthodox, or alot of effort, or whatever, but it worked for me!
