A year ago during Covid I adopted six pacific Sea Nettles from local aquariums that had to close. I have had many moon jellyfish in the past for approximately 10 years. The tank is custom-made from a friend of mine in Southern California called pacific marine labs specializing in moon jellyfish The tank is almost a year old and during the time of cycling I cycled the tank at 78° with seated bio balls,The tanks filtration system is a simple three stage filter system with a 10 gallon reservoir at the bottom for pumps and various equipment(sump)
It is directly under the tank it is shallow there’s not a lot of room for any tall Equipment etc. skimmers reactors.
1.Mechanical filters (Filter floss)
2.Carbon filter ( chemipure blue)
3 Bio ball chamber
No skimmer
The Cycle took a l while but once cycled I reduce the temp to 61° They actually prefer colder but 61 is pretty much the limit. I introduced 2 medium size jellyfish at a time and since dropping the temperature have struggled with Ammonia , Nitrate , Nitrates and phosphates.
The really cool thing is there’s absolutely no algae to show that the nutrients are high because such a low temp.
I want to Install 2 external media reactors 1.To boost up Biological filter was some kind of extreme porous rock like Seachem matrix 2.some kind of phosphate and nitrate Reducer. I don’t feel the amount of bio balls and not having any live rock in there is doing any justice I have put four small bio blocks in the sump area. I have not Noticed anything from those there’s not a lot of water movement in that reservoir. They’ve been in there for about four months.
Here’s the question
Is it because I’m running such a low temperature I’m having such a hard time with the bio filtration and will this still be problem if using other bio filtration media?
PS. As of now I’m doing a lot of water changes but is highly not recommended because jellyfish don’t breathe the water, they are the water
