ah, see I'm hesitant to tell you straight up whether or not you should do
it, since I haven't personally ever seen or used the upgrade. Assuming it
works as-advertised, then I would definitely say its worth the money, I
think its only around $20 and gives you a very significant increase in flow
rate, which is a good thing. But also like I said earlier, I've read some
people say that it is kinda bulky and unattractive, thus my suggestion to
try and get a feel for how big it actually is just by looking at product
pages and finding dimensions, and then decide whether or not you think it
will be unattractive in your tank.
I'll do a brief search for a review page where people who have bought
and used it give their reviews of it. I'd suggest reading those reviews,
then decide for yourself. I'm just trying to protect myself (and you!) from
giving you bad advice :) Here, check out these pages (note that one is
for MJ900 or 1200 only, the other is for MJ400-900.. also, it appears that
more than one company make mod kits for the MJ): http://www.marinedepot.com/ps_ViewIt...551~tab~4.html http://www.petstore.com/ps_viewitem-...111-tab-4.html
definitely read through all the reviews, some are good and some are bad.
But, ultimately you'll have to decide for yourself, unless someone else
chimes in here who has actually had them. Sorry I can't give you a direct
recommendation! But again, since I haven't personally used it, all I can
do is comment on whether or not it "seems" like a good thing based on
the product claims.
Maybe one idea would be to purchase one upgrade kit and try it out...
that way, if it doesn't turn out like you had hoped, you're only out a few
