Is insufficient firterlization one possible reason for the outbreak of an algae bloom (green water)? The reason I ask is because it sorta seems like if there is a lack of nutrients, well the algae wouldn't have nutrients either.... but maybe algae doesn't need as many as the plants??

Last night I turned on my pressurized CO2 system for the first time and within an hour I had almost killed my Kribs. It turned out that I had a drastic drop in PH. From 7.2 to less then 6.0 (I don't have a test that goes below 6.0 but after 50% water change and the rest of my PH stabilizer...

I'm sure these questions have been asked before, but I couldn't find them on the search.... 1.) Where do you go to fill empty CO2 bottles? 2.) Where can you find T connectors and tubing for CO2? I can honestly say that I've never run into these products and services in my day-to-day life...

My DIY CO2 output goes down significantly 5-7 days after making it... so I'm having to replace it about once a week. It seems like people usually say their CO2 lasts about 2 weeks. I know I can reduce the amount of yeast I'm using to make the CO2 output last longer but I'm using a pretty...

I am going to plant my 10 gallon and I've been wanting to get a new filter for awhile now. Right now I have a mini hang on back regular filter. It seems like a canister would be overkill on a 10 gallon and I think I don't want a bio-wheel since that would release carbon dioxide from the tank...

So I just got my CO2 setup for my 10 gallon in the mail but I'm headed out of town next week and I'm having my girlfriend look after my tanks for a few weeks... Anyway... I've never grown Riccia before so I want to be around when I plant it, add CO2, etc... so I can monitor and trouble...

I'm adding CO2 to my 10 gal tank and I am wanting to grow riccia in it. Do you guys think that a 15 w 65000 k regular output fluorescent will be enough light?

I recently did these things to my aquarium: 1. Open Top with Coralife 2x65w lights. 2. CO2. 3. Canister filter (Fluval 304) from HOB. 4. Planted. Now I have this weird film stuff on top of my water that is bugging me (and my butterfly fish). I know some people might say that its the water...

So my understanding of this process is that the yeast consumes the sugar and CO2 is released as a byproduct. My question is this: How does changing the amount of yeast affect the rate of CO2 produced? If thats a stupid question, sorry, but my thinking is that since the yeast multiplies and...

I have a pair of kribs that like to keep breeding. Unfortunately no fry have made it much past the point where the parents go for another spawn and start ignoring the older fry. I think my knife fish is getting a meal. Anyway, whatever the reason for their demise I wouldn't mind seeing a few...

I was looking at buying this canister filter for my 38 gallon tank. It says good for aquariums up to 45 gallons (250 gph) but I've learned to question what a manufacturer claims. Would this work or do I need to go bigger/better?? TIA for any thoughts...

So, yesterday I put together my DIY CO2 system which includes a diffusor with powerhead and the CO2 comes from the yeast sugar mix in a 2 liter bottle. This morning when I checked on it there was a pocket of air at the top of the bottle. I disturbed the bottle and all the air in the bottle...

I have a 38 gallon tank and I was hoping to get about 2.0 - 2.25 wpg with PC lighting. I am thinking about the Coralife Daylight 6700k 65W lights. I obviously can't get the 2.0 - 2.25 range I'm looking for with 1 bulb, and 2 is too much. If I buy the 2x65W fixture, can I average 2.0 wpg...

I just got some new kribs and they, especially the female, keep pestering my 3 apple snails. She is constantly nipping at them and the snails are forced to hide in their shells. They used to roam around all the time eating but now that they have to stay "home" I'm wondering if they might...

Is it true that you don't have to do gravel vac's when you do partial water changes with a planted tank? TIA

For a person's first planted aquarium, is it easier to try a larger (say 38 ) or smaller (say 10)?

Would apple snails destroy any live plants I might add? I have three in a 38 gal.

Does one particular kind of aquarium glue or whatever that stuff is that holds rocks together work better then another? I assume its safe for the fish.

I just got over a case of the ICH and, tragically, I lost my most sensitive fish... my african knife fish and clown pleco. I think I either increased the heat too slowly allowing the ich to really go at them, or they were too susceptable to the meds. Oh well, it was my first try at fighting...

There's one in every family. One bad apple. One who just isn't satisfied within the confines of normalcy. John was one of those bad apples. The young snail had been around plenty of LFS's in his day. Sold, returned, sold, returned... the classic revolving door policy. He just couldn't get...

Like many new to the hobby, I went out and bought some fish to start my tank out without really thinking what I was going to do with the tank. I have since completely changed the direction I want to go with the tank. What can I do with the fish I no longer want? I can't just go flush a live...

I have one african butterfly fish and I was thinking about getting another one. I have read things going both ways concerning keeping multiple butterfly fish together. Some say yes, some say no. Does anyone have any personal experience trying this, or know someone who has? The tank they...

I have an HOB filter that came with a 10gal starter kit setup. It all seemed so economical... Anyway, the filter doesn't have that much power since its a small tank etc... and I'm wondering if its creating enough surface agitation to fully oxygenize :) the tank. How can I tell besides...

I am looking for a few community fish that live on the bottom of the tank and are relatively easy to care for. I could probably add 5 inches of fish. I already have an upsidedown catfish so whatever I get they have to be able to tolerate that guy living down there too. Any suggestions that I...

So, I'm new to the hobby... I had a 10gal when I was growing up, but now I have my first job and I therefore had to go buy my "first" tank. I am wondering what the best method for cleaning a fish tank is. I have a gravel vaccum which I try to use twice a month along with replacing about 1/4...
