I think its time to take another leap.
I still have half my rocks in the curing bucket. Dosing it with 4ml peroxide daily; do it by pulling a rock to sit out of the water and dispensing the HP dose over algae. Wait 5 minutes and put back under water. All the HP eventually gets in the bucket. Ammonia and nitrites at 0, Nitrates at 30ppm today after a 33% WC
yesterday, and phosphates up to a mind staggering 0.04. At least I know my Hanna Checker can make a reading of other than 0.
In the DT, I am also dosing 25ml HP for about 125 G of water all told. I am using a syringe to dose it into the worst areas of algae, and am being very careful to avoid SPS
, as I've read they don't like it. LPS
don't mind the dose at all. The algae is turning white shortly after the dose. Amm, N2, N3 and Phosphate all at 0 still.
Now I think I need to do something to get ride of the algae, pulling it all out is neither possible, nor feasible in a 31" deep tank. I have mentioned the clean-up crew I'm thinking of and its hefty (to get $35 air freight to the island). $200 worth of critters, including 65-100 dwarf blue leg hermits, 24 scarlet hermits,4 lettuce slugs, 3 conches and an algae blenny.
The other thing I'm considering is changing out my substrate which I think is a crushed coral sand mix. It was 1 year old when I got the tank, and that may have been part of the problem, but I rinsed it very well first before reusing it. I would go with a standard arag sand or PFS (haven't decided yet). I would have to suck out about 1/3 each week with water changes (right side, centre, left side) to avoid shocking the entire system.
So, I'm asking the experts opinions, should I get the clean-up crew and hold off or even cancel the substrate change (I guess I should post a pic of it to confirm what it is), or change the substrate first and see what that does.
Did I mention Grr, algae!
I also pruned the chaeto again (3 weeks) and it dried to 13grams of biomass. Still way less than I'm feeding. Stoopid algae.
