Currently running a 75g gallon tank with 30 gallon sump. was misguided and had to learn the hard way. nitrates are through the roof. did 20 gallon water change last saturday, and did another 20 gallon change today. actually think I'm gonna do another 20 change before the night is out. i think my nitrates might actually be measurable after the second change tonight. obviously i got something wrong in my filtering. just ordered a new reef octopus protein skimmer. the one i started with sucks from coralife. looking for any info i get for a noob. I'm planning on getting a bigger tank, and with research into that, I'm realizing i need help. i want lps corals. i got green star polyps, cabbage leathers, elephant ear riccordias, and xenias in the tank now. looking to expand to the red sea reefer 525 xl tank.
