I am having some issues with my Nitrate levels, currently they are at 80ppm, they was 100+ the other day, but a 25% water change has brought them down. The tank is cleanish, but my live rock and other fake rock has some thick algae on there.
I am planning another 25% change on Sat morning, but was wondering about taking out the live rock and/or fake rock and rinsing them off, as well as syphoning whilst cleaning the gravel at the bottom, during this next change....
I was going to rinse with fresh salt water from LFS. I will be getting a fresh supply in the morning you see, so was going to rinse using some of that in a bucket first before syphoning and then topping up the tank.
I can check the Nitrate level of the water I get to be sure,yes. I am using API saltwater master kit (ph,ammonia, nitrite and nitrate)
Tank has been running for about 15-18 months now, just that recently the levels have gone up, and i was going to take the live/fake rock out gently rinse off the algae, then syphon the gravel with no rock in to get the hard to reach areas. Then put the rocks back in and then top the water up
