Hi,

I have a Hammer Coral which is receeded and a white stuff is coming out.

The water parameters seems OK:

Salinity: 1.026
PH: 8.4
Ammonia: 0
Nitrite: 0
Nitrate: 0

I have a 55g sumpless with a Fluval G3.

I went on vacation and the tank stay one month with no water changess.

The corals were all good and now the Hammer isn't good as well as a Green Star Polyp.

Also, I see some cyano forming.

I did a water change when arrived and planning another tomorrow.

That coral is in need of an iodine dip Also You need to check alk and calcium also.
Also what test kit are you using to test nitrates

API test...

I'll check Alk and Calcium...

Sending the results ASAP.

Both on API kits.

Thanks

The API test kit is notorious for being incorrect.
If you went a month without a water change and don't have a skimmer. I don't think your nitrates are zero

That's the same thought I had... I shutted down my skimmer during this period, because there were nobody to clean. I have a HOB Aquamaxx and it's taking a TON of slime now!

I also have a super low bioload, with only four small fishes, but I have two nitrate tests and I tested on both and both are reading zero.

2 mostly deadly thing for lps corals
Alk and nitrates imo.
Check both of them first.
Also can't hurt to do 20 percent Water change
What other kit do you have

Yes. I just find it hard to believe with the canister filter Not cleaning it for a month and you still have no nitrates

i think he does have a aquamaxx skimmer. a canister filter can cause issue if not clean regularly. the op has enough live rock to do bio-filtration. the canister is really useless in his setup.

Well new studies show the sand is probably doing more biological filtration than the rock. But yes I agree with you. No need for the filter. Just adding work to your cleaning schedule that really isn't don't much benefit to the tank

All right,

I had no chance to test ALK and Calcium yet, but the coral is showing improvements. It opened a lot more yesterday and it's looking way better now.

I agree on the API tests quality.

What the test you use / recommend?

Thanks!

I use Hanna for alk, Red Sea for nitrate , Milwaukee for phosphates, Red Sea for calcium and magnesium

Before the filter my water wasn't "polished".

As you know, I don't have a sump, due to space limitation.

I have a 55G "taller" and "thinner" tank from Petco. I might use that tank as sump in a future, but I'm still learning a lot.

I do have an RO/DI filter, and building my fish room in my basement, so it's a long and slow process to me before move to a bigger tank.

I was also skeptical when I bought the filter, with everybody saying that may be a nitrate factory and it worsen than help...

I did a bet on it, just to prepare for this month leave.

Well, anyways, it seems my water improved a lot - I think also because the carbon and I usually was running on nitrates on 20%ish on my API tests.

After installing the filter, my nitrates decreased to 10%, 5% then zero.

I was shocked when I had zero after the month leave. Again, that might be something with my API kits - I had two nitrate tests, so I tried both and ZERO.

I'm looking forward for suggestions on a better kit, but I can tell that I'm happy with the filter and again, super low maintenance for a sumpless tank.

I would by the Red Sea nitrate and test again.
Not saying the API is wrong just saying I don't put much faith into it

I dont get you guys with the canister filter. I have been using one for years on my tanks with no issues. Water changes and check your water parameters

Diana. I been smoking for 20 years. I don't get you doctors who keep saying smoking causes lung cancer

Ps us guys never said you can't run a canister filter. Just saying the work isn't worth the trouble.
Kind of like sand I see you went bare bottom. Probably because you didn't think the sand was worth the trouble. But many people have sand in there tank for years

Good luck with that😂

Oh, also, one thing I remembered here:

My RO/DI water output is giving me TDS of "1".

Is that OK to add this water in the tank?

If not, what specifically should I replace in my RO/DI system?

I do have a 90GPD from Spectrapure. Standard model.

Again, thanks for all your feedback! :)

Should be zero. But 1 isn't bad. But I normally change ny carbon every six months but I have 600 gallon system

Yup... At very beginning it was zero, and I bought the unit in October with no media changes yet.

What do you recommend me to change? Everything or it depends?

Carbon every 6 months it's cheap like 7 bucks each. Sediment filter you can do less but look at it. Di I do once a year

OK!

I'll start with Carbon... I bought the extra media, I was just wondering what to change in first, or change everything at same time. :)

Appreciate your comment.

It seems we have it back on the track...

That may be something related to excreting something or even reproduction??

Anyways, thank you all for your help!! :)

If you indeed have an Aquamaxx Skimmer in play than the cannister filter is totally unnecessary. Get Phosphate/Carbon dual reactor with RowaPhos in place of the cannister filter, RO/DI Water, Weekly water changes of 10-15%, equipment maintenance/cleaning 6x/yr, feeding phosphate free food 4x a week max and controlled lighting you should be fine.

luck

As long as you are keeping up with the maintenance that canister is perfectly fine polishing you're water an running carbon there is slot of folks using them with great success. As far as the smoking analogy to using canister.really ..........
