I've got a 15g nano that's been a little neglected over the last 6 months or so after a new addition to the family.
At the moment it's softies - some mushroom, GSP, leathers and zoas that had mostly been happy.
It's a little overstocked with a clown, dottyback and flamehawk.
Battled dinos last year, got them under control dosing po4 and cutting back on the water changes (both po4 and no3 bottoming out).
Since then things have been OK but a solid mat of GHA has developed. Long enough to annoy, short enough to make manual removal very difficult.
Last 2 months the corals seem to have gone downhill. Zoas receding, leather closed and getting covered in algae, mushrooms not opening as much.
That coincides with my neglect. Basically just a 10% wc every fortnight and glass clean.
Only other thing ive been doing is spot dosing the GHA with 3% peroxide most night - just a little working my way around the rockwork.
I broke out the test kits today expecting high no3 (had approx 50 last time i tested a few month back) but discovered no nh3/no2/no3. Po4 i think was at 0.5 (hard to tell with salifert test kit).
My medium term plan is to replace the substrate and either replace all the rock (it's a few large awkward pieces) or give them a peroxide bath and break them into small pieces.
That's a lot to digest, any thoughts/suggestions appreciated.
