Every site I looked at for aquarium rock backgrounds, it is all for buying
or making these for inside the tank. So, for everyone who has the problem
of what sealer and paint that is safe to use, I came up with the perfect
solution. Make the background to go on the back outside of the tank.I got a
55ml thick piece of polystyrene, long enough to go the full length of my
tank and cut it to height. Use a thin knife or long hacksaw blade heated
over the gas cooker, then it will cut the polystyrene like butter. Try on a
waste piece first. Then shape the rock effect with a heated round file or
something similar, being careful not to burn all the way through, also, I
used a soldering iron for finer detail. Then you can spray paint with one
or several colours, and to finish off, I got an artificial topiary ball
from a garden centre, or you can use one of those sheets of grass matting
for aquariums, and pull off the individual pieces and stick them in the
rock grooves here and there. Believe me, the finished background looks
authentic and very natural. To fix it to the rear of the tank, place it
against the glass and wedge it against the wall with several pieces of wood
or whatever takes your fancy.The big bonus of this method is, it does not
take up tank space, you don't need to worry about using toxic paint as it
goes on the outside, and finally, it is quick, and very cheap to make with
a fantastic end result. Why no one else uses this method for a backgroung
@keatts6865 totally understand. my 125 aint gettin any smaller. im going to
wait..... a very long time lol
Mine is still going strong - the second attempt - if you have seen all of
my videos I did not glue this one in well enough and had to start over! So
Hey, I want to know that cements will absorb water, so i have seen people
talking that after some the background start crumble. so is it true? how
much these backgrounds are stable? The particles of cement are hazard for
fishes or not? if its mixing in the aquarium water then after a while will
it create any poison for the fishes?
