Do the UV water purifiers really help much? I've had some problems with my tank and the fish getting ich lately and was thinking maybe one of these units could help... I have a 14 gallon bio cube reef tank and think maybe water flow might be an issue. I have no interest in setting up a separate hospital tank as I've not the room nor the cash to do so.
NOTE: I do have a power head and keep a pretty close eye on the water and salinity.
NOTE: I am a fairly new hobbyist of just 4 months.
