I can do all of that, but there is still the case of the dying snails.. Wondering if theres something else that's toxic in my tank causing snail deathTo get started treating this issue, you’ll first need to pull as much as you can by hand and with the use of a small brush. Toothbrushes are a great option. Using a fish net will help catch anything that floats away. Secondly, you need to temporarily reduce your light cycle to not more than 8 hours each day and not more than 50% intensity. Third, feed your fish every other day not more than they can consume in 3 minutes. That will be difficult as most reefers love to see their fish eat and be happy. *Do not do a water change for at least 2 to 3 weeks! Be sure to change or clean your filter sock(s) and skimmer collection cup daily. Dosing a beneficial bacteria such as Microbacter7 according to package direction will significantly add to your success. Please note that algae of any species is a culmination of many factors, some of which could be over feeding, poor or non existent skimmer performance, lighting, nutrients, etc. Lastly, add a diverse clean up crew. Trochus snails, 1 urchin per 40 gallons of display, and Mexican turbo or zebra snails have been my army of attack in the past. After week 3, retest nitrate and phosphate levels, (they should be higher than your current readings) change 20% of your tank water, and slowly increase your light cycle.
