Welcome to the second annual EVO Marine Aquarium Journal!
I keep an ongoing tank journal for both the saltwater EVO and the freshwater Spec V.
Highlights for year two of operation:
- No significant equipment changes.
- SNOWMAGEDDON! The great winter storm of 2021 – one that will go down in Texas weather history. We were out of power for about three days. We had natural gas, so I boiled water, put the hot water in 2-liter bottles, and floated on the surface. The tank temp dropped greatly (from 78°F down to the upper 60s), but all the fish and snails survived!
- We bought a skunk cleaner shrimp (our third try), and the thing died in less than a day. I love these shrimp, but we might be done trying as they apparently don’t like our tank.
- The two clownfish (Fanta and Frisco) are doing well – fat and happy. They like to sleep near the return nozzle. So cute.
- Coralline has made a significant increase, which is awesome. It started as a dozen or so pin-head-sized spots in June. By the end of the year, there are pencil eraser to nickel-sized splotches all over the bottom 2/3 of the black acrylic wall.
- Purchased our first coral in March – a red Acan. Followed up with three additional corals by the end of the year (blue acan, hammer coral, and torch coral).
Our EVO 13.5 Saltwater Journal: 2021
1/2/2021:
Changed out 3.2 gallons [12.2 Liters] (of 11 gallons) for a 29% water change.
Scrubbed algae off the rocks. Siphoned and stirred the sand.
Replaced poly pad filter media.

Replaced poly pad filter media.
1/22/2021:
Changed out 3.2 gallons [12.2 Liters] (of 11 gallons) for a 29% water change.
Scrubbed algae off the rocks – I removed the two smaller ones fully and scrubbed them in the siphon bucket. Siphoned and stirred the sand.
I moved the power head to the back (filter) wall. I also scotched all the rocks away to give the power head more room.
1/27/2020:
Scrubbed algae off the rocks. Stirred the sand and blew off the rocks with the pump/baster nozzle.
Replaced poly pad filter media.

Salinity = 1.0255 SG
Nitrate = 0 ppm
Alkalinity = 7.7 dKH
Phosphate = 0.00 ppm
Calcium = 410 ppm
Magnesium = 1,230 ppm
The salinity being low may be causing the magnesium to be low as well. I will add some salt water over the next few days to try and get the salinity back up to 1.026.
2/9/2020:
Replaced poly pad filter media.
Added copepods from podyourreef.com (Tisbe Biminiensis)
2/10/2021:
Salinity = 1.026 SG (just a hair over)
I noticed two very small spots of coralline algae on the back wall, down low (close to the sand).
The snails seem to be lowering the diatoms a bit on the rock work (probably the four remaining Trochus).

Gently siphoned the front/right corner of the tank’s sand and didn’t touch the rest.
I did NOT touch the rocks. The snails seem to be making headway.
2/14/2021:
Removed the bag of Seachem Phosguard. I’m going to go a time without it to see if I notice a difference (if it’s effective, the algae will get worse).
2/15/2021:
Winter Storm! Woke up to a power outage. Tank temp had dropped to 75. Started swapping out a pair of small plastic bottles (with near boiling water inside) to provide heat. Later, switched to (1) 2 Liter bottle.
2/16/2021:
Day two of power outages. I did the bottle trick several times through the night. Still dropped to 70 overnight.
2/17/2021:

Changed out 2.3 gallons [8.8 Liters] (of 11 gallons) for a 21% water change.
Gently siphoned most of the sand – especially around the back rock where snail poop is collecting.
I did NOT touch the rocks.
Algae Watch: the brown fuzz algae that we have been battling forever, has never looked better than it does now. Very low.
So many changes recently:
* Change to Tropic Marin Pro from Instant Ocean (1/28/21)
* Added new CUC including (4) very hard working Trochus Snails (1/13/21)
* Stopped using Seachem Phosguard (2/14/21)
* Added copepods (2/9/21)
* Power outages last week that led to wild temperature swings and a tank blackout for a day (probably didn’t have a big effect).
* I changed the light to a custom setting that was more blue than previously used. (1/20/21)
2/20/2021:
Replaced poly pad filter media.

3/22/2021:
Put back in the newer version of the InTank media tray to lower the water level back down. I’m just doing this to fiddle, and the water level with my modified version was a bit high (water was wicking up into the lid frame and making a salt creep mess).
Cleaned out the pump (took out, ran RODI through it, cleaned inside with toothbrush).

Gently siphoned most of the sand.
New coral is looking good (as far as I can tell).
4/4/2021:
Noticed the return pump didn’t seem to be flowing as well. Took it out and realized it comes apart (the impeller pulls out). It was clogged up with growth.
Cleaned the Return Pump: Brushed and wiped all surfaced clean (including the impeller). Ran the pump in a 1:1 water/vinegar mixture for 20 minutes. Then ran in tap water, then RODI water to rinse it.
It flows much better afterwards.

4/28/2021:
Added a new skunk cleaner shrimp. Temp and drip acclimated. Maybe third time will be the charm.
4/30/2021:
Found shrimp dead this morning. He was stuck in the coral – almost like it was ‘eating’ him. Maybe he died and happened to float into it. Maybe he was getting a snack and got stung. (?).
At any rate, less than two days alive in our tank. I have no idea what happened. Might be our last cleaner shrimp.
5/3/2021:

I have the auto-feeder in place. We are going on vacation in a few days for a week.
A few developments in the tank lately:
* We have baby snails hatching. I’ve seen three and they are shaped like Trochus.
* The pump/heater sections are full of tiny white things hanging on the glass. It appears they are sponges.
* There are dozens of spots about the size of pin heads on the back (plastic) wall. I checked and they are not sponges – it appears it is coralline algae. Also a few spots on the return nozzle.
7/1/2021:
Replaced poly pad filter media.
7/11/2021:
Replaced poly pad filter media.
Tank did very well while on vacation. Only a bit more hair algae on the rocks. Otherwise, no changes. Not even much algae on the glass.
Makeup water was almost empty, so that’s about 2 gallons used over 9 days. (House was kept around 80 degrees).

I’ve been feeding heavier to see if I can influence the nitrate and phosphate up above zero.
Coralline on the back wall is looking better. “Chicken pox” all over with some of the spots getting bigger (from pin point to a few pin heads).
8/12/2021:

8/21/2021:
Blew detritus off rocks with the baster.
Used the tweezers to remove as much of the green turf algae as possible. Some of it came off surprisingly easy. The red turf algae on the other hand, is stuck on there good. It has turned orange from the hydrogen peroxide treatment on 8/20.

(Tested prior to water change)
Salinity = 1.026 SG
Nitrate = 0.5 ppm
Phosphate = 0.03 ppm (I used the high sensitivity method first and it came to 0.12 ppm but I didn’t have confidence as there was so much fluid in the container I couldn’t fully dissolve the powder reagent. Retested with conventional method.

The red acan is receding along an edge. (The other two corals look great.) I wanted to test to check what is going on. Everything seems ok except phosphates. I might want to perform a larger water change next time to get that down and start again with weekly water changes (instead of the bi-weekly that I’ve done for the past few water changes).
A few days ago, I bumped up the peak light intensity. This might have been part of setting this coral off (it is toward the center/side with more direct light than the other two corals). I reset to the previous program to lower the intensity.
9/9/2021:
Added a new coral from Austin Aquafarms – an Indonesian Gold Torch. It has a single head. I trimmed the plug a bit and placed it on the lower front rock. (Furthest from the filter sections).
I used tank water for the dip and acclimation process and replaced with new. Probably amounted to 0.8 gallons [3.0 Liters] (of 11 gallons) for a 7% water change.
9/12/2021:
Blew detritus off rocks and stirred up the sand with the baster.
Changed out 1.7 gallons [6.3 Liters] (of 11 gallons) for a 15% water change.

9/13/2021:
Replaced poly pad filter media.
The blue acro has receded a bit since Sunday. I’m not sure if it was too much hydrogen peroxide yesterday or a stinging effect from the new torch coral. To be safe, rearranged the three corals in front to give more space between blue and the torch.
9/17/2021:
I removed the plug from the torch coral and glued (using super glue gel) it to the rock work.
9/18/2021:
Changed out 1.6 gallons [5.9 Liters] (of 11 gallons) for a 114% water change.
Siphoned detritus out of the filter sections.

9/22/2021:
Replaced poly pad filter media.
9/23/2021:
Salvador (blue acro) is looking better – back to being full and not so receded near edges. I think it’s that the light is getting brighter (It has been in acclamation mode since getting the new torch).

Which tropic Marin salt did you switch to? Are happy with it?
I’ve been using Tropic Marin Pro since the start of 2021. It is very good. Consistent, clean, and puts parameters about where I want them.
I plan to stick with Tropic Marin Pro for the future.
