Great job I'm glad everything is working in the correct direction.Hello everyone and here is an update on my 150! In the works I'll soon be setting up a 2 part dosing to better stabilize my alkalinity and calcium. I was using a glass top on the aquarium and recently switched to a net top to allow more light to penetrate my system. I am losing 2-4 gallons of water per day now to evaporation! I was on vacation from 2/10-2/18 and while I was gone my temperature probe/heater stopped working properly, luckily it didn't overheat but my tank dropped from a stable 77.9 degrees down to a 73-74 degree range. All of my corals and fish seem to be doing fine now that I got the temperature stabalized, but all of my zoas have died. I had 4 separate colonies; 3 of the them are completely gone and the last colony seems to be slowly dying. Attached is a 4o second video of the tank! Enjoy!!!
