I would say it would definately help. How long have you had your tank setup and what is the substrate in it? When was the substrate added? Of course there is always that theory if it isn't broke, don't fix it, but I find even when I think my root feeders are doing great, I throw a tab under them and then watch them grow like crazy. My red rubin sword with a 1/4 stick of jobes under it has been almost producing a new big broad leaf every 2 days.Sir_BlackhOle said:I might try flourish tabs under my radican and marble queen. they both seem to be doing good and the radican is reproducing like crazy, but it may help....?
