I'm hoping people can chime in with the favorite tips to reducing nitrates.
Here's my current scenario.
Bought an existing 55 gallon FOWLR
system that includes the following:
Blue Tang - I know, to big. Remember he can with the tank
Dwarf Angelfish (I think)
It has around 70 lbs of live rock, plus a new 2" - 3" sandbed. I ditched the old sandbed, but laid a thin layer of it on top of the new sand bed.
When I picked up the tank it was in pretty bad shape algae wise. I cleaned it up and it looked pretty good.
The fish were being fed every day. 1st day - 2 cubes of frozen brine shrimp. 2nd day - 1 frozen cube of brine shrimp and back to 2 cubes on day 3 and throughout the week the pattern was rotating like.
All it has for filtration at the moment is a 3 stage HOB
filter that has a sponge, bag of carbon and some sort of bag of rocks.
When i got the tank home I added 20 gallons of new RO
premixed saltwater that I got from the LFS
and the rest was water I had saved from the existing system.
I kept the LR
submerged during transfer.
Days 1 - 4 were great. A pristine beautiful tank. On day 5 a thin layer of diatoms / brown algae appeared. I was running the 50/50 65 Watt Coralife lights for 12 hours a day like the previous owner
So, here's what I have done so far to correct the issue:
Reduced feeding to M,W,F - 1 chunk of frozen Mysis shrimp and a couple of flakes for the Tang. The food is eaten within 5 minutes.
Reduced light cycle to 8 hours.
Bought 7 Astrea snails and 7 Nassarius Snails
Bought 2 Peppermint shrimp to try to battle the aiptasia that was on the LR
Purchased (have not received yet) a Reef Octopus BH-100F HOB
Protein Skimmer that will hopefully get here soon.
I will do a 15% PWC
change tomorrow as that will be 1 week since I had setup the tank.
Current water params:
Ammonia - 0 ppm
Nitrite - 0 ppm
Nitrate - 20 ppm
pH - 8.3
I don't have the means to create a sump system immediately.
So..let's have them.
I'm hoping the diatoms are breaking out cause of the new sandbed and will burn themselves out. But I'd rather not see it my tanks for months if I don't have to.
I'd love to hear any tips the you have employed to combat this stuff! I don't have the means to create a sump system immediately, but will be looking to in the near future.
Thanks for helping a noob!
