water changes

  1. Freshwater and Tropical Fish
    Hopefully I'm posting this question in the appropriate area. Say I'm doing a partial water change, 5 gallons of a 20 gallon tank. My assumption is that I only use enough conditioner to treat the 5 gallons of new water. It would seem to me if I treated all 20 gallons of water I would be using...
  2. Freshwater and Tropical Fish
    Hello all, I haven't had a tank in a while. I used to have had a 5 and 10. I thought I'd try a 20 this time. For filtration, I set up a Sun Sun canister pump and an Aqua Tech 5-15. They are both used. Each from two different tanks. I rinsed them out really well and scrubbed them with a...

    Mini Garden ina Goblet - 1 gallon Freshwater fish tank I just set this up today. Wondering when I should do my first water-change and how much. Here are parameters... one gallon goblet. 1" of organic soil, covered with 3/4" sand. Planted with four little Peacock Ferns and two Kyoto. Lighted from...
  4. Beginner Freshwater Aquarium
    So the adapter for my bathroom sink just does not work. I have garden hoses that can reach from my slop sink in the basement to the tank upstairs. My nitrates skyrocketed quickly and the only other option is to use a 5 gallon bucket, which, it being a 125gallon tank i'd rather not do that. My...

    I have the siphon / gravel vacuum from Aqueon that attaches to a sink faucet. It's just like the Python. The manufacturers of both products promote the no-buckets convenience of removing and replacing water with these tools. To date, I have ONLY used the product to remove water and to vacuum...

    Welcome to another episode of Aquahound's Dirty Little Secrets! In this episode I explain the Nitrogen Cycle aka "The Silent Killer" which is one of the most misunderstood topics in the fish keeping hobby today. Every new tank goes through this cycle and it is important to understand how and why...

  8. Beginner Freshwater Aquarium
    I have had my 55 gallon planted aquarium for about 10 months now, it is wonderful to have! I can't figure out as to how often and how much to do on water changes. I have been taking out 8 gallons every week. I am unsure if that is enough or not, and if every week is to much or to little. Water...
  9. Beginner Freshwater Aquarium
    I have a question I'm hoping someone can help with. I've had my 29 gallon tank up and running for 6 months now. I'm not new to fish keeping. I've ran in to a problem I've never had before. My tank was properly cycled (to a "T") and has done extremely well since the cycle was done. My water...
  10. Beginner Freshwater Aquarium
    its been a while since i have cycled a tank and i'm not sure how often to do a water change. my new 26 gallon has been running a week now and i know it is cycling because i have had nitrite readings of 0.5 that have come and gone. I have 6 fish in it right now and nothing has died or looked...
  11. Cichlids

I have a 75G with 21 fish and right now i'm doing weekly 25G water changes and vacuuming the gravel every time. first...

  13. Cyprinids and Atherinids
    I'm fixing to display my newbie ignorance... I know I need to test the water and change the water weekly in my tank, but do I test the water before or after I change it? Or do I need to test it on a different day?

    I don't know how often to change the water in my 10 gallon tank. I only have 12 fish but everyone says something different! :-?
  15. Livebearers
    I recently had a 10 gallon tank with 4 platy. Yes, I know, I had 3 males and one female, which isn't good. However, all my males were very peaceful, didn't harass the female or each other at all. It was the female that was a character! She chased and harassed all the others continuously, though...
  16. Beginner Freshwater Aquarium
    what is the purpose of changing the water? Is it a preventative measure to keep nitrates, nitrites, ammonia, hardness & the PH from getting to high. If the carbon, sponge, & bacteria in the biomedia keep the level of harmful chemicals at proper levels is it still neccessary to do water changes...
