Green water; how do I get rid of it?
I've recently eradicated a big algae issue in my planted 10g community tank and it has left my water rather green. Try as I might the water stays green. I've gone through about 3 water changes over the last two weeks. (around 40 percent each time) and, while a slightly notable change occurs, the green color is persistent. I can barely see through the water because it is so discolored and it is quite the eyesore. My parameters check out and my fish are doing excellent so I have no worries aside from the nasty colored water.
Any ideas on how to rapidly return the tank water back to a desirable color without having to go through every shade of green imaginable before getting there?
I have neons, cories and ADF's in the tank. Just to rule out anything that could potential harm any of them.
Oh oh, I was wondering if activated carbon would do the trick?
I've also heard of Diatom filters, but I imagine that would be quite expensive.
Also, after doing a little googling I've come to the conclusion that I haven't completely eradicated the algae issue and still have tons of free-floating algae. Thoughts?
I also read about blacking out my tank to kill off the algae but I'm not sure how that would affect my fish and ADF's.
Any advice, guys?
What kind of lights do you have on the tank. Certain lights promote algae growth.
There are numerous threads dealing with black outs and how to perform them and of course I can't find them right now! I grabbed this from a website. If you aren't running Co2 just ignore that part. I wouldn't think a 3 day blackout is going to upset your ADFs, neons or cories:
Step #1: Clean the filter a few days prior to procede with this method.
Step #2: Remove all the algae you can.
Step #3: Large water change (50-70%) and refill the tank without adding ferts
Step #4: Turn your Co2 system and lights off for the next 3 days.
Step #5: Feed the fish.
Step #6: Cover all sides of the tank. Make sure there’s no light in the tank. It should be totally dark in there.
Step #7: Leave the tank in total darkness for the next 3 days. No feeding of fert dosing during the blackout.
After The Blackout
Step #8: Open the light and have a look at your tank. After 3 days in total darkness, the plants might look a bit pale, no worry. There might be some algae left in the tank, we’ll take care of them later.
Step #9: Do another water change
Step #10: Add fertilizers and Co2 and wait 2-3 days. The light should be on during that period.
Step #11: If there is any algae left in the tank, repeat steps 1 to 7 again. You can keep doing this indefinitely until the algae gives up (they will). Don’t forget to do a good water change after each blackout
Alright, this method sounds good. I ripped out all of my plants during the initial algae clean up and currently only have a small bundle left.
The decaying algae won't hurt the fish will it? So long as I do a good water change?
As for cleaning the filter. I did take out the media, cleaned inside the filter, removed any visible algae on the sponge and then put it back in because I've heard it's a bad idea to replace the filter media all at once. Should I worry that there is algae left in my sponges?
As for the lighting. I'm pretty sure I have the proper lighting. I made sure of that from day one and I have only recently had algae issues.
I wonder if I should just cut off a piece of the existing filter media and put that in with new media or if that would eliminate to much good bacteria?
I would just keep your current filter especially since you will need to do large water changes. Good luck I hope the blackout works for you.
I would keep the filter until after the blackout because you do not want to risk a possible mini-cycle due to water changes and gravel vacuuming.
