I have 4 MJ1200's (unmoded until Wednesday) in my 180g. Right now all have Hydor's. Think I could do away with my Hydor's and mod all 4?
The alternative is to just mod 2 and leave 2 with hydor's. Seems like I would get enough flow jolting all over the place with 4 mod's.
My tank is 30" high, and all my MJ's are near the top.
advice?
