Undergravel heater, sand and flourite
Hi;
I have a 125 gallon for which I purchased a Dupla undergravel heater. I was about to add flourite (my favorite substrate), when I looked at Peter Hiscock's Aquarium Designs. On page 29 hes says that you "must" use silver sand to cover the cables. Does anyone knnow if I do need silver sand as a bottom layer? Thanks |

The original Dupla book which shows the cable installation in several places doesn't mention silver sand at all and doesn't mention anything in particular with gravel other than don't use fine sand which packs too tightly. Don't sweat it. -- Need Mercedes parts? http://parts.mbz.org Richard Sexton | Mercedes stuff: http://mbz.org 1970 280SE, 72 280SE | Home pages: http://rs79.vrx.net 633CSi 250SE/C 300SD | http://aquaria.net http://killi.net |

You might feel better spending more on your tank, but these do not help plant growth in anyway. I've used them for 10 years on 7 different tanks. They do not do anything. Tropica, one of the largest growers of aquatic plants also agrees. So.......... Regards, Tom Barr |
