but i went st george aquarium i got what they use! called
RHODORSIL
V2
I made it easy on myself went to a lfs that made tanks! and bought this stuff ?
as for caves dont bother send a pm to
i have purchased caves from bream legend but now have quite abit of slate and wet saw so ill be making my own, so even if i use the clear roof and gutter silicon and let it cure for 1 week its still no good ????
yeap thats right no good
you were planing to take the bosses ay
lol
if i remember correctly it was $5 a tube
good luck with making your own, i here it can get a little messy
Shelley's is ok for caves.(Bunnings) Rhodorsil v2 is the strongest. (what I use). You could use any silicon which is 100 % silicon - acetic cure and does not contain additives. It is safe to use after 3 days but takes a few weeks to get to full strength.
