Hello, I've been into tropical community tanks for about 3 years now and am anxious to start up a nice display tank out of a 75 gallon corner flow, I was thinking a stock of 10 electric yellows and 8 yellow tail acei but I'm open to suggestions as I'm in no rush for the stock and want to ensure Perfect parameters and aquascaping prior to any new fish purchases. That being said that stock was a suggestion on another forum as a "cookie cutter stock" for people that are new with mbunas, any other suggestions I could look into would be greatly appreciated! I've already fitted the bottom of the aquarium with egg crate and a few stones from the elbow river, used the boil method and vinegar test as well as scrubbed the stones maticulously prior to putting in the tank. Yesterday I picked up a 25kg bag of quikcrete premium play sand as per recommendation, washed and added it as well as rigged up a coralife 36" dual t5ho fitted with an actinic and 10000k daylight bulb and a 250 watt fluval heater supposedly capable of maintining temps as high as 88f in a 75g. Today I'll be cleaning out an established 10g tank of mine and adding the substrate to the sump as well as the biomedia to jump start my cycle, will go fish less and will add pure ammonia, again open to suggestion. I've purchased some (Dafco) fuzzy polyethylene particle filters to also use as biomedia ( talked to the manufacturers to ensure they're not treated with anything) am I missing anything? Is there anything else I can add to this setup to help maintain a proper ph? This tank already has pretty decent water movement, however I also have a power head I could install to keep a current near the bottom... Any thoughts or suggestions would be awesome, I will post a few pics later on today. Thanks!
