Lighting for 20g LPS tank

[MerkethMerky]

I have a 20 gallon long and I am purchasing the lights for it here in the next couple of days. I was looking at the fluval 3.0 marine 32 watt for it since LPS dont need as much light and this covers the size of the tank whilst being low PAR.

Does this work? Its just going to be a Euphyllia tank so relatively low PAR needs. But I do want a clam of some kind in the future and I know I will probably need 250+ PAR for them. Would it be better to get a higher watt of similar size for it? Or a whole other light entirely? Lighting has been the hardest thing for me to understand as a newbie so I've left it to the last thing I do lol.

Any help is really aprpeciated. Budget is like $200~

Its ok. If you don't mind a very blue heavy light, the noopsyche minis would work and are in your budget. If you can hang the light, quanta or reef brite led's would work too. AI blade would be another option which on fish tanks direct is $240.
