I don't see why it would be bad, or any worse than a plenum. The plenum, DSB
, barebottom debate has raged on and on and on... IMHO
whatever works for the individual is best. If you are going DSB
and have a soild base structure it probably isn't neccisary or if your DSB
is deep enough the weight will displace and not be a factor. Also most glasss tanks have tempered glass bottoms which is stronger thaat one might think. Plenum users might say using eggcrate might create areas on inactivity and anerobic bacteria pockets aiding in the nitrogen cycle. DSB
advocates might suggest it will do exactly the same as previously mentioned and become a ticking timebomb as a nutrient sink. *shrugs* Do a little reasearch both for and against plenums and DSB
and decide for yourself. Keep us posted on you findings. I am interested to see what you come up with.
