  1. Default Cichlid setup help

    I have a 40 breeder tank and a 20 gallon long sump, I used it for saltwater but want to convert sump into wet/dry sump. Can someone help me with design? Im confused on how the bioballs work and what is the drip tray. What rocks are used in cichlid tanks? Lighting? Also would I need a canister filter or a sump filter would be ok. Pool sand how much sand should you use?

    To use the 20g as a sump you can do 3 things:

    1. Drill the tank for bulk heads
    2. Purchase a hang on the back overflow
    3. Create a DIY overflow using PVC pipes

    You don't have to create a wet/dry trickle filter for your sump. You can essentially turn it into a filtration similar to a canister filter where you have mechanical filtration and submerged bio-media with a return pump.

    About 1lb of pool sand will roughly create a 1" substrate. I wouldn't go more than 2 inches of substrate.

    Tank is already drilled. I thought BioBalls needs water to trickle into. Im confused now. Any designs, pics? I have a sump that I did already for saltwater but im going to freshwater now.

    Bioballs do best in a wet/dry filter, with water trickling into it and not submerged, as you stated.

    In this link you see a wet/dry trickle filter. The sump portion of the filter is the area of standing water, basically the waterline above the return pump. Notice how the bio-balls are not submerged during operation. The water just flows through it from the drip tray on top. Nowadays, I see people use the word sump filtration when they are actually talking about wet/dry trickle filter.

    You can use a sump without wet/dry trickle filtration. I would not use bio-balls for this. I would use ceramic media or K1 Kaldness media.

    On post #4 you can see his design without water, notice there is no trickle filter and bags of ceramic media will sit on top of the pond filters. This is what I mean by using your sump similar to a canister.!!

    On post # 28 you will see the sump filled with water.!!/page3
