Does anyone with a small nano use root tabs? I'm going to rearrange my Spec 2 this weekend. There are several individual jungle val plants that have been growing very slowly. I'd like to replant them along the back of the tank and stick a root tab in their general area, but I'm wondering if a 2 gallon tank is too small a tank to use a flourish tab especially if this tank houses inverts. If one root tab is considered overkill, then can I get away with cutting the tab in half or in fourths? Thanks.
