DIY 3d rock background

[kimmysparks]

ok i have an established tank i am going to decorate. I plan to use foam board to make a rock wall across the back of my aquarium coat it with cement and silicone it to the back.

I have been watching you tube videos on how to do it but the question i have is regarding the cement. I have seen where they say to fill and drain the aquarium like 8 times to wash the cement so it doesnt jack up the pH but thats a lot of water for my 75 gallon tank not to mention all the bucket lifting. Do you think i could fill a container of water and soak it overnight then put it in my tank and be safe?

You really should have a gravel vac/siphon/water changer/faucet adapter... Itll make your life sooo much easier espcially since 1 waterchange per week is recommended.

Either a python or water changer of some sort. I had a python in the past now I have an aqeon water changer that works just as good.
