I've kept fw planted tanks for about 20 years, and started a reef tank this year. Fw planted is a lot more work to me with the constant trimming, I am in the process of removing most of my stem plants to alot more time to the reef tanks. Fw planted and reef tanks are very similar though. I've used co2 and dosing pumps with 2 part ferts on planted tanks similar to dosing a reef. Fw and reef are both beautiful when executed properly.
