Or just blast them off under hot tap water....then soak them over night in a bucket of water with one bottle of hydrogen peroxide added. Safer than bleach and just as effective at killing algae. When finished, just rinse the plants off and return them to the tank. No treating with dechlorinators or water conditioners is neccessary.
Just curious... why is it important to get the algae off the fake plants? Are you worried that its going to make to tank more prone to algae blooms, or does it make to plants look bad? Not trying to be a smarta**... just ignorant!
Maybe his is just a personal opinion, but I think the alge make my fake plants look more natural. Now I'm talking about a little brown and a litte green alge, not green hair here.
I go to great lenghts not to get the small amount of alge off of mine.
Since your plants are fake it will be quite easy to clean of fhte algae.
- you can take them out and scrub the algae off iwth a toothbrush
- you can bleach them(i do this al the time withmy decorations). Just rinse well andi soak in declorinator(a couple times the recommended dose jsut to be safe). ANd add it back to the tank.I have never hada problem.
