That makes sense, I’ve always been back and forth as well, I’ve done CUC first in previous tanks and didn’t have problems, I think it’s all about preference, regardless you’re bound to get algae at some point in the tanks life it’s just being able to manage it that is the real question. I think the slow 4 month process may be the way to go if you’re new to the saltwater hobby, nothing good happens fast! Learned that the hard way yearsssss ago lol
CUC Introduction
Despite high nitrates and phosphates and working on bringing them down, I decided to add CUC first to keep the tank maturing and increase the chances of fish immortality. It was also to introduce coraline algae from the snail shells into the tank.
I tested the water they came in from the LFS just to see how different the parameters were from my tank, so I can determine how much of a gap I have to bridge during acclimation. Salinity was 1.022 little lower than mine, nitrates and phosphates were way off the charts (a lot higher than mine). This was a bit of relief that I'm not doing so bad.
I added 1 trochus snail, 2 turbo snails, and 2 nassarius snails. I expect this is half the number needed for this size tank, but I thought it's a good start to test the waters, especially that I will have to feed them as there is no algae for them to eat currently.
I have been feeding small squares of nori rubberbanded to a rock once every 2 days which is roughly how long it takes them to finish it, and a few xs vitalis pellets once or twice a week. I didnt want to go crazy with the nori so it doesn't make a mess in the tank.
The 2 nassarius snails and 2 turbos seem to be eating regularly and constantly moving around the tank. But the trochus snail is in the corner high up on the glass with little movement all in the same 2 square inches, and I haven't seen him eat.
I've had them for just under 2 weeks now.
Should I be concerned about the trochus snails survivability? Is there anything I can do or feed to get it more active and eating?
Heres some pics taken on the day I first got them.
