My husband Dan and I have had a 200 gallon aquarium for 16 years, however
we have not had water or fish in it for about 5 years.

DIY Aquarium Background

I stuck strictly to Glenn’s instructions, with one
major exception. With the tank being so large I
did not feel I could possibly apply the concrete
to the pieces while they were in the tank. I
decided I would have to coat all of the pieces
independently and then silicon them into place
in the tank.
I was very hopeful this plan would work after all
the time put in on this project. I did not want
anything to go wrong. We were able to get all of
the exact ingredients and after a test run on a
couple of pieces, I decided to screen out the
fiberglass because there was an awful lot of the
fibers in the mix and they could be clearly seen
on the test pieces. I used a screen colander like
Glenn shows in his instructions and it worked
really well. I got the majority of the fibers sifted
out. The only other variation I made was to add
tint to all of the coats.
The plain Quikwall mix is white and I did not
want to have to worry about getting all of the
white covered up. Also, if I got any chips in the
pieces I did not want to see the white layer. For
the concrete colors I mostly used tan, brown,
brick red, and charcoal. Each coat I applied
was a different color. After three full coats of the
concrete mix was applied than I really started
playing with the colors. I mixed up a very thin
mix of fortifier, Quikwall, and coloring and
applied it to the pieces in layers with a small
brush. I had a real rock that I used as a model
for the shaping and coloring. When I got done
with all of the pieces I was not quite sure of the
final result and my husband was really
skeptical.
We waited a few days and I think the colors
faded a bit and eventually looked better to us. I
also knew that they would look more gray in the
tank and eventually be covered with algae
anyway.
We carefully layered the pieces into the tank
applying generous amounts of caulk to the back
and top of each layer. It took an awful lot of
caulk.
My husband was so eager to get the tank filled
he brought up the hose that same evening and I
had to remind him we had to wait for the caulk to
dry.
Two days later it was Saturday morning, April
2nd, about three months since the project
began, and we started filling the tank with water.
For the next few days we had some issues with
some of the layers starting to separate, but my
husband drained the tank down a bit, dried out
the problem areas and re-caulked it. He
eventually placed some other pieces in the tank
to sort of wedge all the layers together against
the top center class piece.
This worked as the layers can no longer spread
apart. After several water changes, filter rinses,
and PH checks we felt we were just about ready
for the fish. My husband pumped water into the
system from a Koi tank we have in our
greenhouse for a biological head start. A day
later we had the water up to temperature and
added the cichlids. We went with an assortment
of fish such as Yellow Labs, Lwanda Peacocks,
Pombo Rocks, Super Ruby Reds, Zebra OB,
Golden Julies, Moori, and 2 Bristle Noise
Plecos.
