yeah thats the plan. i did a really really slow acclimaton of the brackish to marine for the sake of the F8 and their colors are nice and bright, they are very active, eat every time i feed, come up to me when i come to the tank, chase the shrimp around etc. i was a little worried but not so much now because my 75 is just about ready as all my levels(nitrite, nitrate and ammonia) were at 0 ppm, and my ph is at like 7.8 or 8.0 so its cycling very nicely and the water is nice and clear. i put most of the live sand and a piece of live rock i had in the 29 in the 75 the other day as well as put one of my HOB filters i had on the 29 to help cycle the 75 with all the good bacteria. water is crystal clear so im thinking im ok, but dont want to risk it. since i put that live sand and rock with one of my filters from the 29 for the bacteria, should i still expect to see an ammonia spike before the water is good, or does that kind of negate that since the good bacteria is being introduced by me to help it out? but once i get the others in the 75 the 29 is being emptied and transferred to my room. we have like a zoo in half part of our living room. a 110 gallon fresh water tank my roommate has, like a 50 gallon with two red eared sliders we just inherited and now my 75 marine as well as my 29. plus in the kitchen we have my roommates girlfriends leopard gecko and like a 250 gallon(estimated) reptile tank in the process of being built for bearded dragons down in the basement waiting to be finished haha.
