The tubes that are used for "windows/glazing" usually have something about being suitable for water immersion, some even go as far as saying they are safe for aquariums. The Sika brand says on all tubes to use their glazing silicone, clear colour for under water applications
epoxy resin, atleast a week to cure for resin. VS 3 days for silicone ( Selleys or Sika is safe to use 100% just make sure you get the right type, should say on the tube, also has to be clear colour)
Splintered glass is the next best thing to Eheim media, it's one advantage is that it doesn't clog up as fast as the Eheim balls (but less surface area)
I have a picture of a massive planted public aquarium in one of my fish books, can't see much but it looks epic.
What they didn't show you in the video was a guy in an inflatable boat doing some cleaning lol
oh god what is this thread turning into :digH:
Today I bought a twin metal halide light, got 4 checkered barbs to test my big tank (yay they didn't die ) So transferred the other filter over and all the fish into the big tank. Tommorow I'm cleaning the small 350L tank and either shutting it down or leaving it as a hospital tank/holding tank for when I turn the big tank into an african setup
If you saw this in person you'd realise that a planted tank would spoil the background.
Before I even got the tank I had this http://www.aquahobby.com/tanks/e_tank0902.php In my head
