Looks great! I am working on siliconing rock to a large PVC pipe with 3 openings... I can see the DIY thing getting addictive
it really is, I redecorate every week when I do water changes haha
just make sure you cure it for a full 48 hours
24 hours outside of water and 24 hours inside the water
for it to be tank ready
and also make sure you are using the right silicone that's aquarium friendly
I was pointed in the wrong direction by a home depot employee and got the wrong kind
I built the whole house and was waiting for it to cure when I realized what I used wasn't going to work and that I had to start all over and throw away a lot of river rocks
