You absolutely can have a BTA in your tank! The key is good stable water parameters. I also wouldn't feed it very often as BTA's can get HUGE if fed too much and too often. Dosing what you are makes me ask the question of how long your tanks been setup and what are your parameters? Also what kind of lights do you have.
Actually Raythepilot you can do one 25% wc every two weeks and more than likely will be fine. I do a 20% WC every two weeks, I have a skimmer as well as a sump with lots of LR as well as LR in my DT. I have 3 BTA's as well as 9 fish along with several corals of all kinds. SPS, LPS and leathers.
The key is testing with your current animal load on the tank and see when it starts to fall off on your parameters, then do the WC. Sure you can do it more often but I wouldn't unless it was needed shown from test results, mainly high nitrates.
Can you so a WC more often? Sure, you can do as big of a WC as you want daily, but why waste money.
