So so hi guys, started some work on the reef scaping, planning my way to so that no equipment not even the wavemakers will try not to make them visible, started with tje back of the tank.Work is being done by texturing expanding foam, got myself a couple of cans from the US of Greatstuff pond foam but as the tank is quite big and coverage of the foam is quite low and keeping in mind I still will have to coat with resin and crushed coral I continued with the less expensive and more covering home depot expansion foam, tjat why you will see two colours in the foam
