Hi all! I'm new to the forums and aquariums but I'm having some success with my first venture (see tank details). I plan on moving to a larger apartment in about 3 months and would like to build my own acrylic tank (I've researched the heck out of it and feel comfortable doing the construction). Tank details: 72"X24"X24"X acrylic rectangular 180gallon Filter: Eheim Professional 3 XL Aquarium Canister Filter 2080 or 2X Eheim Professional 3 Aquarium Canister Filter 2075 (thinking for added water flow) Substrate: Flourite Live Plants: Broadleaf, Water wisteria Java fern Dwarf hygrophilia Fish: 30 GloFish® (Danio rerio) 12 Albino Cory Cats 1 Gold nugget Pleco Possibly Swordfins or Mollies (leaning away from mollies even though I love them not sure they'd do well with the other fishes water preference) Now, I'm still doing my research but for you have larger tanks, here are my questions. 1. Would you recommend the two filters instead of one for water changes, adjusting any cycling issues etc? 2. Is a surface skimmer something I should look at for a tank this size? 3. If I go with the one filter, should I look for some way to move the water so there's a 'current' in the tank? 4. I prefer lots of smaller fish that are active and school over big fish, Any recommendations for what will et along with the ones I plan on having? Thanks in advance I'm sure I missed some critical things to put in but the excitement of putting this on paper has me rather excited.
