I bought a BC29 back in November and it is my first tank. I absolutley love it. Yes, you do need to be vigilant on making sure the levels stay stable and I change 2.5 gallons of water per week. My tank eats calcium likes there no tomorrow but that's due to it still being really young. I've made quite a few upgrades, new pump (350gph), 144w lighting upgrade, sapphire
skimmer in 2nd chamber.
