UV LIGHTS

What is the UV LIGHT you can get for a 120 gallon salt water tank

Depends on how much you want to spend. What is your budget??

 

[jesse88]

I really don’t have a budget

Don’t use the emergency badge unless it’s an actual emergency.

Welcome to the R2R community!!!

I have used both of these and they are great. One requires replumbing while the other does not.

I have Aqua UV 25 watt on my 125. Very happy with it.

Welcome to R2R glad you joined.

It depends on what you want to use it for. Bacterial doesn’t take a lot but if you want to use it for parasites you are going to need a big one. I am running a 40watt and a 55watt on my 220gal. Both pentair UV‘s. Make sure to flow at speeds they require.

At 120 gallon it's reasonably affordable to get one UV with constant flow to handle both algae and pathogens.

Plan on at least 8x turnover per hour (960gph) at min exposure for algae. This high turnover is to keep up with some species of dinoflagellate reproduction rate.

The high exposure for pathogens (ich for ex) is needed to kill or damage more complex organisms.

So looking at Aqua UV charts (don't buy filter that doesn't have flow/exposure charts) you can see a high exposure at 967 gph for a 40 watt unit.

Getting right sized pump to flow 967 gph with a closed loop set up (all flow through UV filter and not sump connection) will protect your tank from both constantly.

Changing any of the above will require recalculating flow needed at appropriate UV exposure.

Also note that at high end some state up to and over 120000 uw/cm2 exposure needed for some pathogens. You may wish to go with 57 watt unit.

Have you ever had any problem out of them

i broke one of the connectors once (the little blue clear plastic end).. it was easy to replace. other than that, nope. i have 2 of them for years now.. bulbs can get pricey (i have had hit or miss luck with amazon off-brand).

i like the 57W version.

i like the 57W version.

I do too and likely will use for my 75 build just because the form factor will fit in cabinet easier.

Thank you

You don't necessarily need 8x turnover for your UV - not when the typical turnover for a system is 3-5x. I have a 57-watt AquaUV running 565 Gph which is a turnover of about 2.85x. This gives me almost double the radiation exposure for parasites.
