Yes, your plants are heavy foot feeders and don't take much in the way of nutrients from the water column. Byron will have to weigh in on whether or not he thinks you should use both tabs and Flourish Comprehensive. If it was me (and it's not!) I'd use the root tabs approx. every six weeks (breaking the tab in quarters, using 1/4 tab under each plant) and I'd dose with Flourish once a week, being very careful not to overdose as you have a small tank. In my smaller tanks I use 2 drops per gallon of Flourish.
What type of lighting do you have on this tank?
Your betta's gonna be one happy camper in this tank!
I have 1 flourish tab per plant right now in the tank. The lighting is 10k 11w PC and it's pretty bright for such a small bulb but I think it's because the canopy has dual reflectors.
The only thing I am seeing that I am not liking is the flow in the tank with the Tetra Whisper because the water is still pretty cloudy right now. I thought about using an aquaclear HOB filter but the way the hood is designed it does not allow for an HOB filter so I have to use an in-tank. Anyone know of another in-tank filter that allows you to put your own filter media like chemi-pure?
