Laterite quantity, substrate circulation & reptile under-tank he
Regarding the use of laterite, how does one calculate a
quantity to use? I think I saw this information in FAQs, but when
I needed it I couldn't locate the information.
I'm considering the same substrate set-up approach as Granger Ridout,
that is, a base of vermiculite, laterite & fine gravel mixture and fine gravel
on top...awaiting comments to his post.
I have one additional idea I
would like to solicit comments on. Since circulation is important in the
substrate, I was thinking of taking half-inch CPVC with numerous
holes drilled in it and running it
throughout the substrate to facilitate circulation. I was going to
place it on top of the vermiculite with a clear tube coming up from the
network in the back of the tank to add nutrients and fertilizers. A
couple of air stones
could be placed inside to aid the movement of water when CO2 is
treat the substrate, I was thinking of using the "Heat Wave" reptile undertank
heaters by Hagen. There are three sizes up to 25 watts and they are
reasonably priced. Any comments?
