Is it ok to use charcoal in a planted tank? I read somewhere that you have to be careful using it in a planted tank but I don't know why. I am not using a CO2 system but have driftwood that is making the tank brownish and I would like to clear it up using Purigen and charcoal. Is it safe? Thanks

In just over a week the ph in my 125 gal has dropped from 8 to 6.8-7.0. It is probably from the driftwood I put in. The water is brownish and I have ordered purigen but it won't be here til Monday. I have to go out of town tomorrow afternoon. What can I do to stabilize it while I'm gone...

Does purigen remove tannins from driftwood? If not what will? I put a huge piece of driftwood in my tank after I soaked it in hot water for a week and the water has a brownish tint. I would really like it to clear up. Thanks!

Hi, I have a peppered cory cat that I recently moved into a 125 gal. half round aquarium. She looks like she has a cut on the side. There is no fungus that I can see. I finally was able to catch her a put her in a 3 gal. When I put the cories in the 125 last week, one seemed to get stuck in...

My 125 gal. half round tank finally arrived. :thumb: It's set up and the filter has been running since last night. I have some extra media stuffed in my 10 gal. penguin filter that I want to put into the FX5, and then add a few fish to get started. I didn't want to put the media in til I am...

If I get 2 small angelfish and they turn out to be the same sex will they get along when they are mature? I really don't want to get several and wait to see who pairs up and have to get rid of the others. It doesn't matter if I end up with a mated pair because they will be in a community tank...

I just got a kh/gh test kit and I'm not sure what the readings mean. The tank is 10 gallons. The KH is 6 the GH is 15 and PH is 8. Are the readings bad? How do I fix them? Or do the fish adjust? Thanks!

How many pounds of Eco Complete should I get for a 125 gal half round tank? If I've figured correctly the tank footprint is 905 sq. inches. Also when cleaning the tank, do I put the vacuum into the Eco Complete or just vacuum the surface? I've never used it before so any advice is...

Below is a wish list of the fish I want and the temperatures they require. I will be putting these in a 125 gal tank I am getting in a few weeks. They all seem to be ok in 79 degrees except for the Dennison's Barb. Will 79 degrees be harmful to the Dennison's Barbs? Also I have a 10 gal that...

I have a 10 gal with a ph of 8. I'm getting a 125 gal in a couple weeks. It seems that all of the fish I want to put in it want 7 or lower. What is the best way to lower ph and why is it not a good idea to use ph down? Thanks

I've been researching the kind of fish I want to put in my new acrylic tank. I want a pleco. While reading about common plecos it stated not to put it in an acrylic tank because it can scratch the tank. I don't want a common.....I want something smaller, about 4-7 inches. Do all plecos have...

I was wondering how far into the cycle nitrites start showing up. My 10 gal. has been set up for a week and a half. I have 4 fish in the tank and several plants. I used Quick Start when setting up the tank. I have made only one 30% water change when the ammonia read .25 ppm. The past few days...
