this is THE most helpful thread iv been on so far
u guys are wonderful and i am actually starting to prepare the tank for a big change.
i found this site that said he changed his 20g FW to a SW with corals fish etc, this is what he did:
- changed sand, 90% pf sand 10% live sand from lfs
- got 2 powerheads and refugium
- added ro/di water, started cycle on filter
- added base rock/ live rock
- bought 3 LED spotlights that had the sucking plastic things to stick them to tank walls etc
- tested tank and added fish/ corals when it was cycled.
the point i am making, is there were 3 LED spotlights that kept these fish and corals alive, while he still had the norm FW lights set up, so technically we could just stick an LED spotlight at each end of the tank and as long as they are powerful enough, the corals would be fine? logic works or no? x
