Could I go without wc for two weeks?

Hello! We normally go on vacation for a week at a time, which works wonderfully for taking care of fish tanks because I do weekly water changes. But we're considering a two week vacation this year, and I was wondering if my two tanks would be okay. I would get feeding blocks/or automatic feeders, but would everything be okay without a water change for two weeks?
29 gallon
Heavily planted
AquaClear50 and sponge filter
9 female bettas, 6 neon tetras, 4 peppered corys, 1 rubber lip pleco, 5 mystery snails

10g
Split between two male betta
Some plants
Two sponge filters

Pictures attached

 

Yes, that shouldn't be a problem. I once went 9 months without changing water in one of mine (when I say heavily planted I mean it probably 4-5x the number of plants you have in yours). I am not recommending this BTW, my PH crashed and that caused me some problems. I now do weekly changes, but I wouldn't worry about going a few weeks.

 

You have so many plants in the tanks that it would probably be fine. Too frequent water changes can actually be detrimental to tanks. I know someone who just tops off their tanks and only does a water change about once a year. Personally, I try to water changes monthly but don't always get to it. The biggest issue I have found is that my water level can get too low for the filter but as long as I remember to fill up the tank before trips it's not a problem.

 

Thanks guys

 

I actually did a water change today...it has been two weeks..trying to use less water. My fish and water parameters in all three tanks, were just where they should be. I do a 50 to 55 percent water change and I will now be doing it every two weeks. I have 2 75 gallons and a 15 gallon. The two larger ones have plants and the smaller has no plants. Two have gravel substrate and one has sand.

 

I hate to argue with everyone but your bioload is pretty heavy with a rubberlip and nine bettas with 5 mysteries. and other fish. your tank also is not old enough to be considered established. I really dont know about going 2 weeks because your pleco will create an incredible amount of waste during that time and it will all be decomposing. if your tank was a year old it would be a bit different but in the beginning like this any little imbalance tends to be brutal on water parameters

Im not trying to discourage you, just being honest. how far away is your vacation? there are probably some things you can do to prepare if you have enough time

We don't have it planned yet. It'll at least be 3 months away. If you really think it's best, I could get someone to come do a water change, but I don't know anyone who really takes care of fish well...

I wouldnt trust anyone with my tank at home haha. Where do your nitrates sit at normally

 

Your vacation is still months away.
So, do a test now while you can monitor it.
Do a water change on the tanks, add the vacation feeders just like you would as though you were leaving and then monitor the parameters for two weeks or however long it is that you're going to be gone on vacation. Test the parameters to see if they are going to change significantly over that time period. If the parameters don't maintain well over two weeks? Then no, not a great idea for them to go that long. So it might be worth reducing bioload (moving some fish to other tanks to spread bioload), adding more plants (even if just temporary fast growing ammonia sponges like hornwort or guply grass that you remove later), and fasting the fish (those vacation feeders are honestly garbage and most fish can go weeks without eating just fine).

 

In my view the safest route is no feed at all. Vacation feeders or even a failure to an automatic feeder poses a greater risk than starvation and no food means your water parameters should remain relatively stable.
