I have a 20 gallon long aquarium which houses Mollies & Platties Ive used black gravel for substrate in the past and with a black background the colors of the fish really stand out and look great, however it is a pain in the @ss to keep clean. Even with syphoning their is still tons of dirt mixed in. I dont want sand because i hear it causes problems with the impellar on HOB filters.
After looking online what others use i heard 3M sell a quartz black sand which was good but they have discontinued that now ! So im stuck as what to use, my tank has been bare bottom for 2 months now .
I enjoy aquascaping my tanks but they just dont look right without a substrate.
Anybody have any recommendations ?
