Will this work with an acrylic tank? I only see glass tanks in the pics. I have a 180 gallon and am considering doing this if it will work on an acrylic tank.
How do you screen fish, etc. from getting sucked down? Do you use a bulkhead strainer in the end of the inner tank pipe?
Any insight to my above Q's would be great. Thanks.
Its been done many times. Just let it dry. AFAIK, PVC primer and cement are non toxic once dry. Its it used on CPVC for drinking water pipes. I would look at the can to see if it states if it is non toxic and safe for potable water. Whenever I do anything with PVC in the tank, I use black PVC, Blends in well with a black background.ONAGI said:is it safe to use the purple primer as a paint inside the water column? I think that's a good idea but would be nervous about the possibility of it contaminating the water quality in some way.
