A few weeks ago while I was working on some electricals for the tank while pondering on what to use as replacement for the copper couplings that I was planning to use as stand Off for the egg crate subfloor. Then right in front of me was the Answer!!
Those fake rocks are glued with epoxyresin to the egg crate. Hopefully I will have enough true rocks to pin down those egg crates coz I didnt glue them to the MARRETS!!
Sorry about those pic sizes I'll see If i can resize them.
I'll be putting fake plastic plants. To hold down the plants I gooped rocks at the bottom of the plants, so I can easily move them around and not having problem of them floating around
