  1. Angry My undercover filter keeps overflowing?


    0 Not allowed!
    I bought this 25 gallon aquarium a month ago. It houses 7 freshwater fishes. It has an under cover type filtration system where a power head pulls water from one side and introduces it into a tray(located right below the hood) having a white sponge like filter media, and the clean water goes out the other end.

    I have 2 issues:

    1.The first problem is, that on the side where the clean water goes out, the tray has a partition. The water coming out of the filter media flows through a small gap under this partition into another buffer area and then back into the tank. The filter media seems to fit into the tray in such a way that it keeps a very close contact with this gap and thus keeps restricting water flow. This leads to an overflow of water from its site of entry and hence makes the filtration system utterly pointless.

    What can I do? Although the pet shop guy suggested cleaning the media only once a month, I have been doing it weekly till now thinking that too much dirt would again become a part of the problem above.



    2. I also bought Sea-Chem De-Nitrate porous rocks to aid the growth of beneficial bacteria. I am not sure if I used it the right way since the pack said the flow rate shouldn't go beyond 200L/h and since my power head did 1500L/h.
    What I did was, I washed these De-Nitrate rocks well and then I removed the filter media from the tray. I put the rocks into the tray and placed the media back on top of it. This was the only way I could bring down the flow rate. Also, due to problem 1, had I placed these rocks above the filter media, things could have gone a lot worse.

    to AC!

    I would try to trim the sponge to reduce the overflow, or replace it with a coarser sponge cut to fit. Or, remove it entirely and replace with bio-media. Some people here run established tanks without a sponge. I would not, however, remove the sponge entirely if you tank has only been running a short time. Try not to clean you rmedia too often, at least not in chlorinated (tap) water. Chlorine/chloramine kills the bacteria you are trying to grow.

    Also, the de-nitrator rocks, which I have used, aren't really meant to house BB. They will, but are not the most efficient choice. To maximise the surface area for BB to grow on, you need bio-media/very porous rocks or material with a high surface area.

    This is my BIO Substrate Rocks for my 45+ Gal tank. They have a large surface area and I need them for my tank due to a big Pleco in it. Called "EHIEM Substrat Pro" but there are other types you can get.
    Almost 2 Liters of them:

    Is your tank cycled? Even so you should clean the filter about once in 3 months
    When everything goes without a hitch its only then do you realize something is wrong

    What species of fish?
    A true aquarist knows what it feels like to step on a sharp piece of gravel
    do as I say, not as I do- William
    Sandy hook, need lest we forget- steeler58
    I think if someone thinks clownfish are called nemos they should banned from keeping sw tank.
