For the first time in 4-5 months since my 75g cycled, my nitrates stabilized under 20ppm.
I've been adding 5-10 pounds or so of LR
every other week, from the local fish stores, whenever they have cured or nearly cured rock available. (Rock that they've had in for a couple months). I've found adding partially cured rock, 5-10 pounds at a time causes no ammonia or nitrite spike whatsoever.
I'm up to around 65 to 70 pounds of LR
I just checked nitrates, and they're the same they were a week ago! usually the climb about 10ppm every 4-5 days.
Did a 30% PWC
, and nitrates are at 10ppm now.
I'm adding another 5-10 pounds in a couple weeks, maybe I'll actually see it start to decline over time, instead of creeping up like its always done.
I'm still hoping to eliminate the HOB
filter, which holds so much crud in it - every time I turn it off, change/clean filters, etc., stuff just shoots out of it (and yeah, I have a filter pad over the intake), it still gets in there.
Also I'm building a new 20g sump/fuge this week, which should give me a lot more room for the fuge, and a separate, filtered area for the return pump, to keep crud from being sent to the tank any time the fuge is disturbed by topping off, PWC
