How are you all doing with your systems and the ARID? please share
Hi robbous,
I took down all my tanks a few months ago due to a temporary move.
C30 is in storage and I'm using the E24 on a new startup CadLight 70 (skimmer less from day 1). I started this tank using the ARID E24 basically 5 days after adding water, salt & rock. So far it has grown Chaetomorpha exceptionally well, had to prune the growth after 8 weeks
It's taken my N03 down to zero but the P04 is sky high (tank is heavily stocked with wrasses & fed 3x a day) so I am guessing that I need to start dosing N03 in order to facilitate the removal of P04. I'm first thinking of using GFO temporarily to bring the P04 down to workable numbers first.
So based on my experience with the ARID reactors, the problem in the past with the previous systems has to be due to the years of using both sulfur denitrators and bio-pellets reactors in the 2 separate systems. While the E24 kicked in towards the end before I took the system offline, this system never used bio-pellets but did have a sulfur denitrator for years. The C30 system ran large amounts of bio-pellets prior to the C30 and that system never caught on with the Chaetomorpha. Possibly something that the bio-pellet polymers leave behind in the system, go figure.......
In summary,
The newly restarted E24 works well in growing Chaetomorpha, faster & better then an average refugium IMO but.................you need to understand the nutrient removal process with macro algae to effectively keep P04 to a minimum in an enclosed system. Just slapping an ARID onto a system and growing/pruning Chaeto will keep N03 at bay, so much that you might not be able to remove any P04 and that's a no no if your trying to keep any type of SPS.
Follow Joe's practices of dosing N03 in order to export P04, then the ARID will work as advertised
