Damn, and I thought that I covered it all!!! I may have one more lying around...looks real good, 1 thing add 1 more valve between the reactor valves and water discharge valve so you don't have to shut of 3 valves and readjust.
Yes rich, I am going to secure it to the overflow and silicone all sides....love the rock work, looks really interesting. just a couple of questions.
1- is the acrylic going to be siliconed on all for sides to the overflow. if not you might have stagnant water their.
2- how are you going to clean the side glasses, they look to be very close the the glass.
3- how much room do you have against the back glass, will you be able to have enough flow to stop detritus build up.
I gave a full explanation in the post where the pics are. So i wasn't sure.probably ment what did u use to stick the rock onto the overflow box
