I’ll say I recently lost a small Derasa clam after it starved out In 100~ μmol.I have this new clam coming tomorrow and looking to place it on the sand (fine sand) with about 160par of light from my X15 Pro lights. Will this be ok ?
Great feedback. I will adjust my lights to accommodate the clam and take readings.You're going to need more light, so I would focus on providing the clam more light than worrying about parameters. I'm not saying you should ignore water parameters, but nutrient levels don't really matter much in this regard, especially NO3. I would suggest 200-250 as a starting point. A healthy growing clam might be able to adjust to slightly lower light, but it's not something I would suggest from the start. Also, you'll want a more "full" spectrum daylight, not heavy blues. Clams come from very shallow waters, so heavy blues are not favorable. Plus, clams look like crap under heavy blues, in fact I'm not sure why anyone would put a clam under heavy blues, as it kind of defeats the purpose of keeping the clam. In short, you're gonna need more light. Post a pic when you get it.
