Hello reefers!

I have a 70 liter net soft & LPS reef tank that's been running for about 5 months now, everything was doing great up until about three weeks ago when I did my first ICP -
Now im fighting two fronts:
1. I got a high reading of Tin - I checked all of my equipment which is brand new and checked for any screws or other metals touching the water (everything was fine) and im coming to the conclusion that its more likely my feeding got that Tin in cuz I was mostly feeding frozen artemia and spirulina.
I switched to dry foods and did a few 15% water changes, I'll be sending my next ICP in a week.

2. My second front is very low nutrients and a ciano-bacteria bloom: at about the three month mark I added 250ml of seachem matrix to my sump as I was advised to from a local dealer who Is a real expert around here, I think that dropped my no3 to 0 and now my po4 also dropped.
at start I have a bloom of hair algae and also bubble algae which got in a tank with a coral I got but now im facing a ciano bloom on top of that - to battle this I started manually cleaning the rocks and glass, siphoning through a micron sock and putting the water back so I wouldn't drop my nutrients any lower.
Ive been seeing a lot of videos about this, some said I should dose no3 and po4 slowly but some say I shouldnt let my tank get used to dosing and just stop water changes and up my feedings.
would love to get some advice from you guys and hopefully get my tank on track.
I will add that my corals are looking great! everyone seems to be happy and healthy and so so beautiful and I want to keep it that way and Improve as much as possible.

another question I have is about dosing:
I started to use red sea's complete reef care 4 part system and switched to fauna marines ready2reef.
I dose 3ml daily and everything seems to be balanced tho my magnesium is a bit on the lower side (1250ppm)
From your experience - which system does a better job? or rather which system is better for the long run?

here is a breakdown of my system:
My tank is a 60cmx40xcmx40xm with a back sump.
I started with dried rocks and sand, in the sump I have 250ml seachem matrix and another bag of media ceramics.
Im running the bubble magus qq2 protein skimmer and a bubble magus pump feeding a 1/10 HP chiller.
For lights I'm using the Pop Bloom Rl60.
a 11w uv lamp, some activated carbon in a micron bag
my heater is connected to my Inkbird 308 alongside my chiller and the temp in the tank stays at 25 c.
an ATO system of course and a 1200L/h return pump.
For wave maker I have the Jebao slw-5 and I'll be adding another one soon.
needles to say I use rodi water with 0 tds.
I use Redsea blue bucket salt

for livestock I have:
2 lismata shrimps and 1 fire shrimp
a cute pom pom crab
some nasarius and turbo snails
and a red sea urchin
and 2 feather duster worms

for fish I have:
2 small clown fish
1 small doctor wrasse
1 kinda big sand sifting goby
1 algae grazer blenny
1 gorgeous neon dottyback

Corals:
I have an amazing 2 head holy grail torch (third head on the way)
a big healthy acantophylia
a variety of zoas
a 7 head candy coral
dunken coral
a 5 head acan
and few more soft and lps, I forgot the names XD


Glad to be here and thanks in advance!

Welcome to Reef2Reef. 🙂

Think about creating a tank thread.

It will be interesting to see the follow up tin level on the ICP. Perhaps create a thread specifically injuring about the tin level in your tank.
I am not going to lie your tank is pretty heavily stocked for it's size. Algae or cyanobacteria issues are definitely common for the age of the tank.
I dose Neophos and NeoNitro. The idea that a system become resistant to nitrate and phosphate dosing seems like an urban myth. I am inclined to think adding the media dropped the N/P too quickly.
Sounds like you have a well planned system, equipment wise.


Create a tank thread so we can see your tank.

Welcome to Reef2Reef!

You tend to get more "welcomes" than answers here in the meet and greet section of the forum. I'd suggest reposting your questions to the general sub-forum, that way you'll get more eyes on your questions 🙂

Good luck!

Will do!
Thank you for the honest answer 🙏🏼

The nutrient (NO₃ & PO₄) levels we consider "normal" in our tanks are orders of magnitude above those of natural coral reefs. I wouldn't worry about reading "0ppm" on any of those tests as long as there's visible growth. Adding more nutrients will just feed the cyanos, and feeding more fish food instead of dosing dedicated nutrient solutions (see DIY NH₃ and DIY PO₄ recipes) has several disadvantages:
  1. You don't really know how much nitrogen and phosphorus you're adding to the tank, so you can't really plan to raise nutrient levels to a fixed target, and worse, you can't control them independently from each other.
  2. It takes a while for food to break down into dissolved nutrients your tank can actually use, so you might add food, see no improvement, add more, and then suddenly get a spike in nutrient levels. At that point, cutting back on feeding won't stop the increase, because there's still "old" food decaying somewhere. You end up just accumulating detritus in your tank.
  3. Adding food doesn't just add nitrogen and phosphorus, it also adds organics (carbon), which are hard to measure and which we don't know much about yet. People have long speculated that organics may play a big role in cyanobacteria blooms, which makes sense considering that carbon dosing helps bacteria grow (even though cyanos have access to inorganic carbon as well, they may still benefit from organics). We don't know for certain if organics play a big role in cyano blooms, but it's just another "unknown" variable added to your tank that's difficult to control.
Note that most organisms prefer consuming ammonia (NH₃) directly over nitrate (NO₃), because they'd have to reduce nitrate back to ammonia anyway to assimilate it. This requires enzymes based on trace elements that can deplete quite rapidly, so it's better for them to take up as much ammonia as they can, as fast as they can.
This means a 0ppm nitrate reading doesn't tell you much about how much nitrogen is actually available to the different organisms in your tank, or whether nitrogen is actually a limiting factor for growth.

I hope this helps a little with deciding how to proceed with your issue. Happy reefing!
