So, since I have increased my lighting, I have seen a little bit better plant growth, but also a bit more algae. Not a serious outbreak, but enough to annoy me. I went ahead and ordered a powerhead, because I am not really happy about my flow towards the left/back side of the tank. Now, I am trying to figure out where to put it? I don't have a diagram of my tank or anything, but I run two externals: one on each back, side of the tank. Basically I have normal outlet pipe pouring into the right hand side, in the back of the tank, and then a spray bar on the left side of the tank, running along the side wall of the tank. The spray bar is aimed at the glass, rather than spraying out, because my angels and apistos don't like too much flow. I am thinking somewhere along the left side of the tank, underneath the spray bar, pushing slightly down and along the back?
Also, I have planted up my tank a bit more in the last couple of weeks, and I am thinking about changing my dosing regime. I was dosing TNC Lite and using root tabs before, but as I have increased the amount of plants I was thinking about something like Excel + TNC Complete possibly? Does this sound like a better possibility? I am still not ready to go down the pressurised C02 route just yet, but does liquid carbon lower PH much, like pressurised does? I just want to make sure as my PH is 6.4-6.2, and I don't want it to really drop much lower. Thanks for any advice!
