    1. The only higher-power waterproof hosts I was aware of are from Lazerer. I purchased this one.
    2. My research indicated the Eagle Pair were the best available and appeared to be used by most serious lasers hobbyists. I purchased 2 pairs through Survival laser which is where I purchased the 1.8W 445nm.
    3. I haven't been able to locate a high power 405nm yet. I'm waiting for someone to produce one in a waterproof host.
    4. Nothing new yet - Current efforts detailed earlier in the thread.
    5. Both methods are viable. Lasing through the glass is the simplest, but operating submerged allows you to get closer, reduce potential reflections and use your hand to sheild the beam endpoint from the livestock. It also dramatically increases the thermal duty cycle. That said, both methods work well.

    One other observation - After extended lasing session (Xenia) I noted that there is about a 20 point drop in ORP (440-420) which gradually recovers over the next few hours. I'm uncertain what is causing this, but it seems reasonable that organics might be released into the water column.

    I've only noticed this thus far when lasing Xenia and I have not noted any negative impact form any other corals in the tank (including those within an inch of the targeted pests.) I run ROX 0.8 carbon on a continual basis.

    Thanks fsu1dolfan :)

    In addition to the already determined roles lasers can play in aquaria, I theorise it might also be a useful in cases of RTN. In essence, cauterizing a border, thereby separating the healthy tissue from the area of RTN. Thankfully I haven't had it occur to test.

    I'm interested in using a laser to control mushrooms. I would guess that they would be more difficult than xenia. Have you tried a laser on a mushroom? If so how well did it work and was there a change in your water quality?

    Guy in our local club just bought a 405nM and glasses. Can't wait to try it out!

    Finally got my laser in the mail yesterday. Thus far I've only tried it on some GSP, anthelia, & protopalys, but it seems promising already. Love hearing that snap, crackle, pop coming from the pest corals!

    I just got mine a week ago. It is an amazing tool for the aquarist. Aptasia and mojo are easy with it.

    Both lasers (waterproof 1.2W and non-waterproof 1.7W) continue to work very well. I find that I am working more from outside of the tank, alternating duty cycles with both lasers. Every pest targeted (except for Xenia) has been easily eradicated with the laser. Xenia continues to be a challenge. I've been able to contain it, but haven't had the patience to completely remove the larger patches.

    I haven't had time to work on developing in-tank shielding. For me, it has not been critical as the clowns in my tank rarely leave their host. I'm convinced the laser can be a very valuable tool as long as safety protocols are observed.

    thank you. if i do intank i can just shield my other stuff with my hand. but if i go outside of tank i will need a shield. how well will they work on mushrooms. i been trying to get rid of a lot of mushrooms but they keep growning back.

    Submersible 1.2 watt blue works very well!

    Although there's waterproof model, I could be still paranoid with regards to its lifespan if repeatedly immersed in tank. So, I could wrap it in clear plastic bag I suppose?

    I don't think this method is viable for our use. The example laser used is a very lower power, fixed-focus laser "pointer", not burning lasers. This design "waterproofs" only the front of the laser. You could not submerge the entire host, eliminating most benefit.
