I hate for this to be a lengthy question but I have to explain. I chnaged my 2 year old 125 tank over to a 100 gallon about 2 months ago. Went from CC
to Southdown sand 2-3 inches thick. I have about 100 lbs of LR
and added another 35 lbs of base rock as well as 50 lbs of rubble rock into the sump/fuge. (Also the fuge is new too as I have Calupera (sp) growing in there now. In the 125 I NEVER added CA
, buffer....nothing. I went from regular FO
lighting to VHO
(440) watts and immediatelty saw coraline growth that wouldnt stop. In the 125 the lights were about 2 ft off the waters surface.
Now on the 100, the same lighting system is about 2 inches off the waters surface and NO
coraline growth at all. As a matter of fact the coraline has faded. All levels are perfect....trates/trites 0, ammonia 0, PH
8-3 to 8-4. AK 2.5, CA
380, phosphates .4 also. However again never monitored the CA
or AK in the prev tank. I now have to add kent super buffer each day to keep the PH
up. I also add CA
daily as well. (seachem)
What can I do to get the coraline growth again? I actually did a water change of about 30-35% when I went from the 125 to the 100. I was told to start using Kalkwasser which I now have but havent used it. I only have 4 small fish and 3 shrimp and 1 anenome.
