Hey guys. So this past week i noticed my tank is developing alot of algea. it is green algea. i also think it might be green bubble cause i see little bubble like sprouts on some rocks and sand but not many. it is mainly on my sand bad. i am going to do a water change on saturday. could it be because i leave the lights on too long? i usually turn my lights on at 3.30 pm and turn off and 10.00 pm. to 7 hrs and 30 mins? sometimes i turn off at 9.30. it is not always at the EXACT time everyday. can it also be because of the powerhead not circulating enough in the tank? my tank seems to have alot of low in the middle but not in the front. maybe changing my powerhead position will help? i also got 4 pnds of new fiji liverock a week ago. maybe introducing them had introduced algea also from the rocks? my chromis r still stressed due to the new rocks. they wont eat the pellets, BUT i think also the reason they wont eat is because they might have been wild caught. And i read wild caught chromis fish only eat phytoplankton in the water. when i bought them at petco they were adult size. the kind og lights i have are a current usa nova extreme 2 18w. one actinic and the other isnt. it's 50/50 and 10000k for the bulbs. i just started my tank on september and the lights were brand new in packaging.maybe also i did feed the pellets and since they dint eat them it just landed on the sand bed. i also dont have a clean up crew. just on snail. maybe i should think about getting a good clean up crew.
also: i noticed this bloom drastically after i did my water change last week and i shifted the lights a little back. i also skipped a day of topping off. my chromis fish r hiding in the rocks. i also moved the powerhead and noticed it was alot after that.
i did stir up the sand a bit during the water change to get the nutrients out, but i think i made them waterborn and released alot of algea during the change. i syphoned some sand out also.
i am not adding any extrea addtives to the tank, just doing water changes
