So, three weeks ago, I moved everything over from my 29 gallon to my 75......used all the sand, all the LR, all the water, and some water from another established tank. I made a major lighting upgrade, from an aqualight pro with two 55w, 50/50's and a 150 watt MH 15k.........to, that plus two 175w 10k MH's. The last couple of days I have had some diatoms showing up........now I get why its showed up on the new plumbing devices.....I built a sump, and the return lines have it and so do the intake and returns on my closed loop.......but some has been showing up on the sand and even spots on the LR. My water is testing perfect though. I am almost afraid it went into a mini cycle but like I said...water tests are great. Any ideas?
