I have planted quite a bit of crypts into my tank recently, some doing okay, some are growing like mad, while some have just started to melt, mostly wendtii 'toprica'. I know melting is normal for crypts, but I want to know whether I should start putting spikes under those melting crypts or maybe I should wait under they grow back?

Thanks

I suggest waiting until they reappear.

I have had the best luck just not messing with melting crypts at all. Give them time and they almost always come back, whether submersed or emmersed.

If crypts are low on nitrogen, and then you give them a significant dose of nitrogen, they often will melt. The best policy then is to keep the nitrogen at measurable levels (around 5-10ppm NO3) while they recover, and don't let it fall down to zero again.
