No not at all IMO, I was just going to suggest using it if you hadn't already. Looks good, I think you're going to need a new tank to get any better shots :wink:

I think he means programed auto (P) which allows you to set up all your parameters manually but selects both shutter speed and aperture. Not really ideal plus you're already shooting in aperture...

You could try manual focus and focus on your center DOF which will give the biggest range. I suspect the tank glass is the bigger issue though, I've seen those 10 gallons bow pretty good which could...

Yes much better, considerably better when you consider that you're closer than the original, it's still a little softer than I would expect though. Are you auto-focusing or manual? Also are you using...

So you want me to add water to the alcohol? I'm not sure that will work, sounds like a headache.

Yeah fractional distillation would be the best way to reuse the alcohol but this is something I'd rather avoid. Our production staff are not the most careful people around and I don't mean to say...

OK so the mat is out, it absorbed the alcohol as well and the solution that did make it through contained the same amount of oil. Basically in this application it's just expensive cloth.

That's kind of what I was thinking, a separate unit to filter the alcohol between washes as required. I've never heard of a chemical R/O before, could you elaborate? If it's anything like the water...

Like I said if it's still it doesn't matter. If the water is stagnant what will move the coral?

The one thing I liked about that lens was how small the aperture gets. Remember this one? Check the...

Yes your shutter speed will be slow but that's fine if things are still, make sure you use your remote or timer. The slower speed will compensate for exposure, you set the offset to -0.7 to be a...

I've heard of people using sand filters to remove oil efficiently, any experience?

A good start, what you need to do is turn the flow off and get that thing to sit perfectly still. Take a nice slow exposure, keep your aperture up in the high mid range and most importantly get that...

Impact is equal to mass times velocity so it's possible to cause a lot of damage at low speed if the mass is large enough. Best to leave it to the investigators but I'd say it's possible. Not sure it...

Similar to "adsorb-it"? Do you know where you source it? I'd be interested in trying it but yeah I'm uncertain how it will work with the alcohol since it actually dissolves the oil unlike water.
