I totally didn’t have this in mind of it all not working out I ordered my sump Monday the pet shop said it would be ready by Friday so I phoned him Friday and he phoned his supplier and the supplier had forgotten or so he said but will defiantly have it Monday and the hole was supposed to be drilled on Friday but the person was going down to saldwana for diving and said he would do it Monday as well , so all out of my hands and for the previous times I really wanted my tank looking a bit better and was warned to not add anything and didn’t listen but I am new and we are all ignorant and don’t want to listen I now get why it has to cycle and plan on doing it properly now thanks , but could you please tell where I could get piping cheaper and what size I would need of I drill a 38mm hole thanks .....
