Add some salt or other substance (like glycerin) to increase your fluid density. Add slowly. Hold off on surf for now you have quite a bit in there.
what bulb is in the grande first of all. Next you may need a second coil. I have never kitted a grande though.
1) Make sure your bulb is a 100 watter.
2) I read my goo kit instructions and it said to use distilled water only. Reverse osmosis (R/O) may be the problem, not for sure though.
3) In the instructions, it says to use 10 milliliters of surf for every quart of water. I think that calculation may be off a little, due to my last lamp I goo kitted. I redone a 52oz lamp which is about 1.6 quarts. That means I should have used around 16-17 milliliters of surf to get a flow going. I actually used three times as much surf (45-50 mills) in order for it to start flowing, but it is flowing great. I understand what Critter is saying about not adding anymore surf, but I think you may not have added enough yet.
4)Try adding some Epsom salts if the surf isn't working. I went back into the library, on this site, and people say to add it slowly. From what they say, it doesn't take much.
Hope that helps
not sure of the specific gravity of the RO water you are using and its relationship to the SG of DI water (i think they are both 1.00 at room temp., but i'm not 100% sure), but it may be to blame. i would dump it and replace with DI water. if that doesn't work, contact the company. their stuff is made to flow right out of the jar with no extra tweaks.
One thing I do notice is that you have the cap off, you need to leave that on, your allowing heat to escape making it harder for the lamp to get going. Also you dont need to add any epson salts to a gookit. Just use about 60 ml of surf and just wait man. Gookits need to break in too so you may not get flow right away just have to be patient.
