All: I set up a 10 gallon tank for angel fish fry. The fry were doing well and most were surviving for over a week. During the work day time, a white infection of something occurred, causing the entire tank floor to look like freshly fallen snow. This engulfed the fry, thus no survivors...

Tonight, I had almost 10 fish, Rainbows and Columbian Tetras, die suddenly. My water chemistry is ok and within normal limits, nothing to cause this, except for my O2 level (from a cheap kit, albeit), which was low, low - well below 100%. In the last week, I had angel fish that bred, but the...

Aquarium Advice: i am doing some preliminary research on new light fixtures. I would really like to purchase an LED fixture, but it is cost prohibitive, so I am comparing T-5 lighting. I have a 125 gallon, planted freshwater tank and currently running a fixture with four 96-watt compact...

I have a Coralife compact fluorescent, 72" lighting fixture, with 4 96 watt compact lamps. One of the lamps went out and I just bought a new set of lamps. When I replaced the burned out lamp, there was a small spark upon lamp start up and not the new lamp does not work. I am hoping I can save...

A few weeks ago, my tank had a major crash. All the bio-filter completely failed and I lost most of my fish in one day. I have been monitoring the chemistry and doing frequent water changes, although the last week I have not due to being out town for work. Ammonia has remained 0.25 or 0.50...

I have had a problem with angel fish getting cloudy eyes and what looks like an infection between the eye and mouth. Sunday, I changed most of the water, cleaned the filters (the bio-filter looked to clean to be active), treated with Para Guard, Amo-Lock, and buffered the pH with CaCl. The pH...

Aquarium Advice: Once again, I need your help with blue-green algae, or cynobacteria. I have had a severe infection since summer. I vacuum out what I can, wipe what I can off of the glass, clip away dead and infected leaves. I do a 50% water change weekly. Although I missed last week (first...

Hey AA guys. I could use your advice and information. I have an algae problem that has gotten out of hand and now I really need some input to correct and, hopefully, solve the issue. The algae I have is the thick, smeary, dark-green algae on the leaves of plants and the glass, especially...

Do any of you have any opinions on "Chuck's Planted Aquarium Calculator", which is available from Greg Watson's web site? I was looking at the "calculator" this week and plugging in my dosages and goals of dosages for my tank. The results greatly exceed his target levels and are consistent...

Does any know what a good starting dose for iron chelate from Greg Watson's would be? I do use Greg Watson's trace, but my iron test reads 0 ppm. I have some SeaChem Iron (liquid), that I am using up at a reduced dosage to supplement and the entire tank looks better with it. I'm just not sure...

Hi AA guys. I need your help again. I have had major problems with green algae and associated green water for months now. In a previous discussion with you guys, I was also losing fish and losing plants. Currently my fish are all looking good, my plants look good and bubble out O2 like crazy...

To everyone who gave me some advice and help -- THANKS! A brief update. I did another partial water change today. Tank looks better, algae getting under control. Current water values as follow, I used both an Aquarium Pharmacuticals and Red Sea test kits: pH- 7.0 to 7.2 (AP vs RS) NH3- 0...

I need help! I have a 125 gallon freshwater tank, which has been extremely healthy for the fish. Recently I added plants, with 384 watt light, CO2 injection, timers, and so on. Added plants. I had a major algae growth, which was cured with Algae Fix for planted tanks. Plants did not look well...

I am planning on purchasing a new aquarium this month and would like your opinions on filter options. I am looking at a 125 gallon for freshwater fish and plant life. I am currently looking at two Fluval 404 filters with 340 gpm each and a total of 680 gpm. I have also looked at the Rena...

Hello. I am an experience aquarium guy with a 75 gallon fresh water and considering upgrading to a 125 gallon fresh water tank. 15 years ago, I had a 15 gallon tank and had extremely good luck with plants, but have not had any luck with the 75. I have heard that I don't have enough light for...
