Should I do a 100% water change?

Yeah I only have 3 fish now. Don’t plan on adding anything anytime soon.

FWIW, I like to stock light and I only have three fish in my sumped 29 gallon, a pair of mature clowns and a sixline wrasse. I probably wouldn't have more than four fish in a 30 unless they were really small at adult size. I like giving fish room to grow and less fish means less waste.

This reply made me laugh haha. You are correct 6 month old aio with a most likely dead shrimp and now very possibly a dead goby. Haven’t seen him in a few days. 30 gallon tank running carbon and chemi clean in a media basket, skimmer and filter media. Here are my most recent parameters.

Youre running chemiclean or ChemiPure in media basket?

I’m running chemipure blue sorry. Little pouch, put it in the middle chamber of my media basket. Carbon on bottom, then chemipure then filter media on top.

 

[vetteguy53081]

ok- scared me. I use and trust ChemiPure

This is a 30 gallon tank that is 6 months old. Already cycled added corals yaddayadda. Now I’m getting a diatom bloom on my sandbed. I recently got a Hanna nitrate checker and it’s the first time I tested my tank for nitrates since the cycle. Tested 70 ppm. I blamed the addition of the goby for the high nitrate level though. Now my goby is nowhere to be found and my nitrates are maxing out my Hanna checker at 75ppm. Here is a picture of the sand bed in the tank

Are you sure those are diatoms? The way they are sweeping and dark really make me suspect some type of dinos. I recommend getting / borrowing a microscope and confirming what you have.

Some dinos are toxic. I wonder if a diamond goby sifting sand with toxic dinos could be fatal? I really don't know - just thinking out loud there.

Just ordered a microscope off Amazon so we’ll find out tomorrow.
