  1. a question:
    Will a Brita water pitcher be able to allow a person to use normal tap water when filling a canister filter with water after cleaning it?

    The situation:
    When I clean my Cascade canister filter I want to not allow normal tap water to kill all the healthy bio media.
    Until now I have had to take my cleaned filter to the aquarium and then begin the messy operation of dumping cup-fulls of aquarium water into the filter to fill it before I can close it up and get it going again.
    I always end up with a ton of water dripping over the clean glass of the tank, and all over the floor, and all over me too.
    I got to try to find a way to fill the filter with water, yet not use un-treated tap water that will kill my bio media on contact.


  2. I agree that putting the drain through the wall makes the most sense, but my concern would be freezing temperatures during the winter months. Insulating the pipe can be done, but there'll still be some cold transfer back into the gallery, and the risk of any retained water freezing in the pipe and creating an ice plug. Will the outlet be underground, or above ground with a strainer to keep critters out?

  3. I like the idea of one big pipe going through all of them. Like one big 20 foot pipe and connect all the tanks with a pipe from the tank and I would put it at a small elevation going down so you would not get stall water in the pipe

  4. alright well you had a problem with mice with your other system do you think allowing an open tube to go directly outside would be a good idea for the situation of allowing rodents to possibly get in through a pipe and plug it up…. the other problem you have is well the water that you drain out possibly contaminate your well

  5. If each pair of tanks (upper and lower) is connected to the sump underneath, why not flow water into (and overflow out of) the sump directly?
    It might be neater, and easier, than trying to flow into the top tank directly?

  6. @The king of DIY it maybe im wrong but wouldn't the method of only adding fresh water to the top tanks in the racking system mean the bottom tanks would only be getting excess diluted water instead of the fresh water they would get in a normal water change. That sounds problematic at best if I missunderstood someone please correct me.

  7. I always wondered when people set these systems up… doesn't the water that is being added have to be at the same temperature as the aquarium water and also doesn't it need to be conditioned?
