    What's the general consensus on a back up heater?

    nice one, glad I asked. I see there are these thermostats without the science phone connectivity which are about half the price. is it worth spending the extra to be able to use it with an app?

    What's the general consensus on a back up heater?

    I have a hydor inline heater, thinking of sticking a normal heater inside the co2 reactor I'm making just as a back up, it's made with a 20" filter housing so there's a fair bit of room for one. good idea or not worth the bother? I've not used the hydor heater before so I'm unsure of how...

    Redone the last bits and now on to the leak testing. I stick a piece of brown paper down under the tank as it shows up the water if it leaks, if it has a leak it will show up pretty much immediately. Normally they leak in one of the bottom corners but I made a point of plugging these up...

    Tank Bracing?

    the glass looks thick so would probably be ok, find out how thick it is then check on an aquarium calculator. could always just remove them and if you feel they're needed, stick them back on again.

    Healthy bit of “it’s gone wrong so I’ll have to redo it update”. When the glass was originally cut the sides were cut so it was a 50cm square and so was the base. The edges of the base were arrissed but the edges of the side panes were ground and polished to give a bevel. Therefore the tank...
