The smallest poppy pipe is a little larger than a golf ball, def. smaller than a tennis ball. I have it on my 60H, but I think it might be a bit large for a mini-L.
I'm using the cal aqua nano fluxus on my girlfriend's mini-L and I'm not a fan. The way the flow is directed (down) blows away the soil and sand sometimes if the flow is too strong. Same situation with the violet pipes.
For a smaller tank like a mini L, I would go for either the do!aqua jet or ada mini jet pipes, or try to find the regular looking lily pipes. these I think are the best because the flow isn't pointed down, so you don't kick up your substrate.
Exact answer I was looking for! Thanks for your help. I figured the violet and the fluxus would create a problem with the down flow. May I ask what filter you have on the mini-l?
I've asked GLA when they'll be getting more fluxus sets in and they said by next week. I'm glad I've had to wait for them because I would have just ordered them without putting much thought into it. Which led me to this thread.
+1 on this! I also received a response from GLA saying their fluxus set should be in no later than two weeks as of 3/4/13. I'm thinking of getting it for my ADA 45-f
Visually they look very similar but it states the JP-1 produces a strong current whereas the MP-2 produces a moderate flow. If I adjust the flow on my filter will the JP-1 perform like the MP-2? Or is the $40 difference worth it?
Get the ADA, the violet glass jet tip is pinched to increase pressure which just makes water flow harder directly across the tank. The ADA product will distribute flow better which I'm sure is what you're looking for. I'd get a P2 though if it'll fit your tank and filter. The dispersion of flow is really nice and it'll aerate the surface well if near the top or slightly out of the water.
