hey bb owners
Ive left my bb tank go unattended for about 2 months
just had a 10 gal water change done on it thursday. when I ran some tests I found my nitrates to be up to 20 ppm wich is deffinatly to high. so this morning I did another water change of 12 gallons and tested again there still at 20 ppm. how long do you think it will take to come back down and how much more water should I change. my tank is 90 gallons w/ 30gallon sump 2 months ago I did have them down to 0 ppm need to get it back there thanks for all the help |

It takes time my nitrates were at 50 ppm I went bb and removed my bioballs.It may take some time.Your rock is what will help and feeding.You may want to run a remote dsb or someplace where the nitrates can sttle and be consumed.I am running the nitrae spong medis in a phosban reactor but because I made so many changes I can't tell you 100% that it works.Other people have had no sucsess with this type of medis.Calerpa in the sump will help aswell.

If you have nitrates in a bb tank there is dirt somwhere. Either its in the rocks or sitting on the bottom. Put some ditritus in a cup and wait till the next day. The nitrates will have risen along with phosphates
 When dirt is presnent its based entirely on how much biological export you have (ie- corals, chaeto, skimmer, ect.)

Its a good idea to have a refrence sample for alk test kits. 1.1350 grams of baking soda in 1gallon of distilled water=10dkh. Check your alkalinity test kit! Algae is Mother Natures phosphate remover Current Tank Info: 220 galon mixed reef. |
