my tank is a stander RR 75gl tank with a 20 gl sump with a mag 9.5 for return . I have a aqua life skimmer running wet + a magnum 350 running 24/7 (mag 9.5 for the cl and 2 maxi jet 1200 that are on when the T5 lights are on)
As for lighting I am using a orbit light that come with 2 T5 running like 12 hours and 2 150 running like 8 hours.
Life stock are
1 powderbrown tang about 3in-4 in
1 Scopes tang about 3in
1 foxface also about 3in
2 false clown( 1 are 2 in and the other are 1in)
1 Six line wrasse
a whole lots of snails and some hermit crab
2 tiger tail cucumber( split last week) + 3 starfish
I feed them 1 ever other day and spot feed my LPS every Sat.
My T5 buld are new, but my MH are about 6 months now and my RO/DI are about a year( TDS ready are 1) and I do 10-20% WC weekly
The last time I had cyano I did WC every other day and it went a way in about a month.
I am thinking it could be any 1 of these 4 thing
1 MH lights need to be change out
2 RO/DI filter need to be change out
4 30+ dead snails since Feb meeting. ( 20 of which was dead a day after the meeting and I thought the crab could use it as feed and shelter) about 10 more die leater of which I got from saltwaterfish. I still have 30+ snails in the tank. ( please do not ask why I have so many snails)
The reason I am saying cyano 2.5 and wolfie .5 is that cyano are also bulding up in my sump which I was able to take out.
Any thought on how I could fix this cyano problem?
I can change the MH buld tonight and also already order new filter for the RO/DI unit
