Hello!
After 2 years of stepping away from the hobby I am trying to get my tank back to a good point where i can start adding coral and fish again. I never completely shut the tank down but did not complete a water change in those 2 years, i only topped it off with RO water when the pump started grumbling at me. The lights have been off the entire time so no problematic algae has appeared and feeding has been extremely sparse, the only living thing in the tank is one (very hardy) clownfish.
All equipment has been cleaned and is functioning - it is a 250LR (including a 50lr sump) tank with a Jerabo SLW-20 Sine wave maker, a Bubble Magus Curve 7, 2x filter socks which get changed weekly, a Ocean Free Hydra Stream 3 Depurator and i am setting up a refugium fitted with a cheap ebay light (https://www.ebay.co.uk/itm/325605756199) the refugium has around 5kg of seachem matrix bio media in filter bags along with some live rock rubble.
i have completed a 70% water change and the Nitrates are still at 40ppm, i plan on doing another 60% water change this weekend which theoretically should take my nitrates to below 20ppm (i also completely cleared out the sump of detritus and did my best to clear detritus off of the sandbed and rockwork), the only place i think that i could be leaking nitrates would be the sandbed. all other parameters are within reasonable amounts, theres plenty of benifitial bacteria so ammonia and nitrite should not be a problem. Temperature is 26 degrees celcius.
finally there is no clean up crew, due to the high levels of nitrate i didnt want to add any too soon, what cuc should i introduce and when? there is plenty of algae to eat so i think theyll be some happy snails etc when they are introduced, to be clear this is a mature tank filled with bacteria and microfauna.
would love any tips on resurrecting my tank, my big concern is nitrates because id ideally not have to try and combat an outbreak of hair algae right away!
i will take some photos and upload them when im home from work for reference.
Thank you for reading
