During my water change, I syphoned about 2.5G of SW
tank water into my 5G bucket. Then I individually rinsed my LR
in that bucket, gently rubbing it with my fingers and my palm. No cuts, thank goodness.
I had another bucket so I was placing cleaned LR
in there. I also cleaned whatever artificial plants. I cleaned all sides of my tank with the magnet thingie (even the back). Red and green algae all over the place, it was filthy.
Then I syphoned 2.5 more gallons of water, syphoning from the sand bottom. More algae rushing into the bucket. Then I added the contents of my other 5G bucket with water and Instant Ocean marinating the day before with a powerhead in it. Then the rocks back with a new arrangement.
I am currently marinating another 5G bucket of Instant Ocean/Water and will be replacing 5G more tonight.
What a nuisance those algae. I rid my tank of as much algae as I can, including the light canopy. Wow, I almost forgot how bright and beautiful my tank was. It was like this green-lighted tank before, very ugly.
Thanks for all your advice!
